I installed the debugging symbol package for glibc but couldn't find a package
for ghc. If someone could point me to a debugging symbol package, then I could
provide a more verbose output of gdb.

Version-Release number of selected component (if applicable):
ghc-6.10.3-3.fc11

How reproducible:
Just run "ghci"

Note: I filed a bug upstream about ghci segfaulting on PPC a long time ago:

Stefan, perhaps you could try and see if ghc-6.12 will be any better here.

Further, I don't think Fedora has resources to work on this alas,
so echoing Conrad: best to push on this upstream.  Note that upstream
don't provide Linux/ppc builds any more (and we don't have ppc64, etc).

I tried SVN snapshot 20091015 but the problem still persists.

I understand this completely if resources aren't available. Fedora is not
responsible to fix such things and according to Conrad upstream is already
informed. So I will close this bug as WONTFIX.

Thanks for informing upstream.

Just to be clear (for future readers of this ticket): GHC on PPC still (mostly)
works, just not interactive mode.

Segfault also happens with 6.12-RC1 fwiw.
