Comment 2 Ai Locke Shinseiko (Wizzleby) 2010-06-06 19:48:35 UTC
I can confirm these test failures here, but can't track down from whence they emerge. Recommend RESTRICT=test until I can talk with upstream about this.
Comment 3 Ai Locke Shinseiko (Wizzleby) 2010-06-06 20:27:42 UTC
I forgot to mention in my last comment, that Mr Bones does not seem to be able to replicate this behaviour. Updated ebuild with RESTRICT=test is in gamerlay overlay until I (or anyone else) can track this down.
Comment 4 Ai Locke Shinseiko (Wizzleby) 2010-06-07 00:03:20 UTC
This is an issue with games-util/grfcodec built with gcc-4.5.0. Optimizations in gcc-4.5.0 seem to break grfcodec, leading to invalid compression, causing the opengfx test failure. Using -O0 fixes. Will attach a patch for the grfcodec ebuild (which hopefully won't require revbump, as gcc-4.5.0 is still masked, and this bug is exclusive to gcc-4.5.0.

Comment 5 Mr. Bones. (RETIRED) gentoo-dev 2010-06-07 00:05:10 UTC
I'm not changing the ebuild to work around a masked and seemingly buggy gcc version.  If it's a legitimate issue with the opengfx code then I'm interested, otherwise this is a WONTFIX.

grfcodec-0_pre2306.ebuild.patch

Inherit flag-o-matic, filter optimizations, and append -O0.
This is now also in gamerlay. With this patch, which should only affect those of us testing gcc-4.5 (the issue exists in 4.5 branch built yesterday too), the RESTRICT=test can be removed from opengfx (it should never have affected users of stable/~arch gcc anyway)
Comment 7 Ai Locke Shinseiko (Wizzleby) 2011-05-04 14:30:42 UTC
This has been fixed upstream, so fixing bug 365957 will fix this too
Comment 8 Tupone Alfredo gentoo-dev 2012-10-31 13:42:13 UTC
Version affected has been pruned by me. Thanks
