[Bug 907515] New: ghc 7.4.1 and 7.4.2 compile a correct gtk2hs program such that it crashes with a segmentation fault
by Red Hat Bugzilla
Product: Fedora
https://bugzilla.redhat.com/show_bug.cgi?id=907515
Bug ID: 907515
Summary: ghc 7.4.1 and 7.4.2 compile a correct gtk2hs program
such that it crashes with a segmentation fault
Product: Fedora
Version: 18
Component: ghc
Severity: unspecified
Priority: unspecified
Reporter: garrett.mitchener(a)gmail.com
Description of problem:
I wrote a Haskell program using gtk2hs. It works fine on Fedora 17 under ghc
7.0.4. However it crashes with a segmentation fault when compiled on Fedora 18
or rawhide(19). The crash occurs the first time an action added to the gtk
loop with timeoutAddFull runs.
I wrote a minimal test case that triggers the problem and posted it here:
http://hackage.haskell.org/trac/ghc/ticket/7629
It seems to be a compiler or run-time-system bug in ghc 7.4.1 and 7.4.2 or
possibly gtk2hs, because the binary built on F18 or rawhide crashes when run on
F17, and the binary built on F17 runs without a problem on F18.
Furthermore, if I disable selinux on the kernel command line at boot time, the
crash vanishes in F18 and rawhide. I don't know why-- the crash doesn't
trigger any selinux error messages, just a segmentation fault.
Jens Petersen reported to me that the crash does not occur on 64 bit test
machines on Fedora 18, but he confirmed that it does occur on 32 bit test
machines.
I've run into pointer alignment problems with ghc before, where alignment
pragmas in C modules are somehow broken when the C module is linked with a ghc
program, so that may be the case here?
Version-Release number of selected component (if applicable): ghc 7.4.1 and
7.4.2.
How reproducible:
Every time
Steps to Reproduce:
Compile and run the test program posted in the haskell.org trac bug report
http://hackage.haskell.org/trac/ghc/ticket/7629
I'm also posting the bug here in case someone else runs into it.

[Bug 880135] New: Compile GHC packages with -O2
by Red Hat Bugzilla
Product: Fedora
https://bugzilla.redhat.com/show_bug.cgi?id=880135
Bug ID: 880135
Summary: Compile GHC packages with -O2
Product: Fedora
Version: rawhide
Component: ghc-rpm-macros
Severity: unspecified
Priority: unspecified
Reporter: dag.odenhall(a)gmail.com
Problem:
If you want to compile your Haskell application with -O2, only parts of it will
be - most system packages are already built with -O1. All your own code is
going to link to those prebuilt binaries.
Does it matter?
Respectable people in the community claim -O2 really does produce better code:
http://stackoverflow.com/questions/11108746/difference-between-ghcs-o-and-o2
Cons:
The fedora packages will take longer to build.
Counter argument:
This shouldn't happen often though, and I guess is done by some build service
[koji?]. Users will just install prebuilt packages with no compilation time at
all and benefit from optimized binaries.
Footnote:
This is only about building the fedora packages with -O2. Our cabal-install
package should not be changed to default to -O2 for user compilation.

[Bug 911725] New: ghc-ghc-devel not required?
by Red Hat Bugzilla
Product: Fedora
https://bugzilla.redhat.com/show_bug.cgi?id=911725
Bug ID: 911725
Summary: ghc-ghc-devel not required?
Product: Fedora
Version: 18
Component: ghc
Severity: high
Priority: unspecified
Reporter: vadie.developer(a)gmail.com
Created attachment 697959
--> https://bugzilla.redhat.com/attachment.cgi?id=697959&action=edit
script used to measure size of the package installed,although one could see it
through packagekit
Description of problem:
I am the culprit for this bloat problem
https://bugzilla.redhat.com/show_bug.cgi?id=750317
ghc-ghc-devel is for hacking on ghc, it is the entir ghc platform(compiler,RTS
etc as a library). This pacakge should not be part of base install
Version-Release number of selected component (if applicable):
ghc-7.4.1
this package takes up too much space (~ 240 MB installed)
and 34 MB
puts considerable strain on bandwidth and diskspace (OK not so much on
diskspace,but would be nice to get rid of it)
How reproducible:
just install ghc, 'yum install ghc'
Steps to Reproduce:
1.yum install ghc
2.say yes
3.
Actual results:
installs static library of entire ghc, which is not required for those
Expected results:
should not install ghc-ghc-devel package as part of base install.
Additional info:
This bug, is due to another request by me regarding quickCheck. Bug 750317
https://bugzilla.redhat.com/show_bug.cgi?id=750317
*note the title changed*
This is what Jens wrote : "
> Maybe we really want the ghc base package to be a meta package
> that pulls in "everything" to make the initial install friendlier
> for newcomers.
Ok, ghc-7.0.4-36.fc17 should provide a base metapackage
which installs all of ghc (ghc-compiler and ghc-devel).
So in future if you install ghc you will have a working
QuickCheck, etc out of the box.
"
I should have said no to it at that time itself, but i was not very
well-informed (not that I am now, just less ignorant),by adding ghc-ghc-devel,
we have internals/implementation of ghc as static library not static/devel
packages of quickCheck,parsec etc. {I am pretty sure about this}
I think it is correct and OK (infact necessary) to provide, -devel packages by
default for libraries of haskell, like ghc-parsec and ghc-parsec-devel, ghc-xml
and ghc-xml-devl,ghc-pango and ghc-pango-devel etc.
but ghc-ghc-devel is going too far. Only those who hack on ghc need this
(specifically who want to hack on this particular version others will track and
program for latest git/darcs version).
I think, it is possible to make this change. no ghc-ghc-devel in base
install,but whenever one installs any other library corresponding -devel
packages should also be installed
I didn't realize about this space problem, untill I ran out of space on my old
Fedora 16 on my root partition, found out that ghc installation took ~530 MB
installed space.
I am not sure about ghc-compiler package though, anyone more experienced in
haskell packaging can chime in.
I think this thing, needs better testing and some discussion so no need to
hurry out the changes, so that we make sure we do the right thing.
