Can't reproduce, fine here

[Comment 3 Ben Kohler 2012-12-23 19:25:27 UTC]

I have seen this kind of behavior from time to time, depending on my CFLAGS & CPU type.  For quite a while I was forcing CFLAGS="" on this package to prevent segfaults.  Working fine right now, though.  We need to see crucify's emerge --info to have a chance to reproduce this.

[Comment 4 Bartosz Brachaczek 2013-01-06 21:55:18 UTC]

I've also seen it on my machine. It was fine with -O0 (or just empty CFLAGS), and it was starting to fail with -O1 and higher. But now after several days it calmed down, it just works with each flag combination, I can't explain it.

I guess we need to contact someone with amd64 asm knowledge or just the upstream to review crucify's patch.

[Comment 5 Ben Kohler 2021-03-23 19:53:36 UTC]

The code this patch touches has been heavily modified since then, can you please reopen if this still affects 21.72?

Thanks
