I need to change the wording: It is a clang-test-issue. I switched ffmpeg to gcc compiler, and test does not fail.

I do not know how to get a backtrace in the running emerge process. If you help me I can do it.
Comment 8 Sam James archtester Gentoo Infrastructure gentoo-dev Security 2022-10-09 23:09:22 UTC
Sorry, I'd missed your reply. I'm not sure how to make ffmpeg's test suite run under gdb because it uses a wrapper.

However... I came across this bug when adding a patch for a Clang 14 issue reported in #gentoo.

Looking into the test you mentioned which fails, I get https://reviews.llvm.org/D105169?id=368033#3069158 (which is linked in the patch I've added) which mentions ff_seek_frame_binary. I suspect it's the same bug :)

So, please retest with 4.4.3, but I think it should be fine now.

Thanks for the report and I'm sorry we didn't get to the bottom of it sooner.
