Description Tomas Mraz 2007-07-23 16:18:14 EDT
w3m crashes on x86_64 immediately with segfault. I don't know whether it crashes
on other architectures as well.

The crash is in gc library so I'm cc-ing gc library maintainer.

Comment 1 Jens Petersen 2007-07-24 00:54:50 EDT
Reproduced with current packages in development.
(Doesn't happen with f7 x86_64 for me.)

Could you try reverting to gc-6.8 to see if that makes a difference?
Comment 2 Tomas Mraz 2007-07-24 05:24:58 EDT
Yes, reverting gc to 6.8 helps. And rebuilding w3m against gc-7.0 helps too. So
that means ABI break in gc. So all dependencies of gc should be rebuilt.

Ccing owners of the above packages.
Comment 4 Denis Leroy 2007-07-24 05:34:05 EDT
I would prefer if gc were held back to 6.8, since it's only in updates-testing.
This is a gc bug after all, it's not meant to break ABI. Looking at the gc
mailing list, there seems to be a number of issues with 7.0, i.e. ABI could
break again with further 7.x updates.

For Fedora 7 that's clear - there should be no ABI breaking update. But for
Fedora 8 I'd leave that on the gc maintainer. Rex?
Comment 6 Parag Nemade 2007-07-24 05:38:50 EDT
on Tomas Mraz request, I already started w3m build on koji for devel branch.

Comment 8 Parag Nemade 2007-07-24 05:47:10 EDT
w3m-0.5.2-2 built successfully against gc-7.0
Comment 9 Denis Leroy 2007-07-24 07:19:15 EDT
Reopening for F-7. I submitted a patch to work around this for bug 248700.
Comment 10 Parag Nemade 2007-07-24 07:22:00 EDT
will wait for new release of gc for F7 and then accordingly release new version
of w3m for F7 only.
Comment 11 Tomas Mraz 2007-07-24 08:17:28 EDT
I think that for F7 the gc should be fixed which is the bug 248700.

So no need for reopening this one.

(IMHO gc should be fixed for F8 - rawhide too.)
