Description Jukka Ruohonen 2006-11-08 03:24:05 UTC

Games-strategy/freeciv-2.0.8-r2 segfaults when compiled with -ftree-vectorize. Tested only with amd64 but other platforms might be affected too.

1. Steps to reproduce: add -ftree-vectorize to CFLAGS.
2. Suggested solution: a flag strip for ftree-vectorize.

As this is easy to reproduce, I added no preprocessed source nor emerge --info.

Just be sensible and use "-O2 -march=k8 -pipe" if you want things to work.

Yes: I agree, while being mostly sensible, too. Just thought it could be to some minor degree useful to note about unsafe/unreasonable flags (though bugzilla is not the best place, at least when appended with non-trivial severity).

This bug still appears to exist - any chance of getting the flag stripped?

Obviously having no CFLAGS will always tend to result in fewer bugs, but it would be nice if things like this could be left open so that they get resolved the next time the ebuild gets bumped for whatever reason.
