[FFmpeg-devel] [PATCH] gifdec: workaround old gcc 4.2 mis-compiling code

[Michael Niedermayer]

It appears gcc forgets to increment the byte stream pointer at -O3
I was not able to spot a reason/excuse for it to do that. It
also disappears if an av_log() is placed in the function.

This should fix the gif fate failures on open & free bsd
