Comment:
--disable-optimization without --disable-asm is not possible on x86-32.
gcc is too buggy for this. On 64bit, gcc has twice as many registers so it
should work.
You can thus either enable optimizations, disable asm or compile for
x86-64 if your platform supports it
You can also use --disable-mmx --disable-runtume-cpudetect instead if you
prefer
Iam closing this as invalid as its a gcc bug not a ffmpeg bug. But iam not
opposed to consider some workaround if theres some volunteer who wants to
maintain such workarounds.
