--- Comment #22 from Bernd Schmidt <bernds at gcc dot gnu.org> --- Created attachment 37674 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=37674&action=edit Candidate testsuite addition Here's a reduced version of the testcase. Could you verify that it passes on PA (after the patch, or with -fno-expensive-optimizations before it)? There are confusing numbers in the table in main, I've had to change some (but not all) of them to match the actual output. I double checked with an actual ffmpeg build.
