Description
Using avcode56.dll, Firefox crashes when playing H264 videos with the OS/4 kernel. This is due to variable not aligned for AVX and explained here, http://www.voidcn.com/article/p-vtipwtsk-cu.html
Fix is to add --extra-cflags='-fno-common' to the configure command line. Tested with avcode57.dll.
Compilation also fails with missing poll symbols, I'll attach a patch to add libcx support as well.

Yes, the first crash was from the RPM/YUM build. The patch I posted was against the official upstream tree.
This should be left for a couple of days as still investigating and it might be better to just configure with --disable-avx.
