I tried building with -O1 but that didn't help.

I wonder if moving to ghc-7.8 will help.

(http://s390.koji.fedoraproject.org/koji/taskinfo?taskID=1441705)

The failure seems specific to s390.  It builds ok on s390x:

I think the problem will be the compiler process trying to allocate more than
1GB of heap or other memory. s390 has only 2GB address space per process as
opposed to the usual 4GB on other 32-bit arches.

--- Comment #4 from Jens Petersen  ---
Ah right - that makes sense then.

Okay I will try later to play with heap size setting
to see if we can make it compile on s390 too.
2GB of heap still seems like quite a lot but yeah
looks like this lib pushes the limits a bit.

Okay sorry for the long pause.

I tried building with 1GB heap with the change below
but it still fails in the same way.

I guess the problem is that it actually needs more VM (not less).
So unless I am mistaken the only solution is to exclude s390 for now.

package

How long do you plan to continue to support Fedora s390 btw?

For now I committed a change to pkg git master to exclude s390.

http://pkgs.fedoraproject.org/cgit/ghc-haskell-src-exts.git/commit/?id=d701a...

It is not built yet but I can backport it to F21 if you like.

To "get further" will need a similar change to hlint and ghc-hgettext.

--- Comment #7 from Fedora End Of Life  ---
This message is a reminder that Fedora 20 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 20. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as EOL if it remains open with a Fedora  'version'
of '20'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora 20 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora, you are encouraged  change the 'version' to a later Fedora 
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.
