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.

Fixed upstream in https://git.ffmpeg.org/gitweb/ffmpeg.git/commit/78062c6d71324fa89708211213b4267d2a57b806. * Fix UB in ff_seek_frame_binary-crash causing a crash with >= Clang 14.
