Please look at:

Your message spawned from the "[FFmpeg-devel] [PATCH]
avcodec_decode_video must set PKT_FLAG_KEY" thread. That is called
thread hijacking. Google can help you identify why that happened and
how to avoid it.

The bugreports page says to use gdb "If you encounter a crash bug",
which is not your case.

make test works by generating some sample image/audio, encoding it
with a bunch of encoders, and decoding that. It will then check that
the md5sum of the encoded and decoded files match a reference which is
in the SVN repo.

The output from make test is not supposed to be a bug report "as-is",
but it should help you locate a bug. You should try to find out why
the encoded/decoded files differ on your platform (preferably by
comparing against another system where make test passes).
