Building mesa with "-march=native -O3" causes some 32 bit games to crash at
start since "gallium: Force blend color to 16-byte alignment" patch
(d8d6091a846ac2a40a011d512d6d57f6c8442e6a). This happens using both opengl or
nine. Everything works as expected using "-march=native -O2".
tested games are:
Native:
The Talos Princible (32 bit) -- Always crash
The Talos Princible (64 bit) -- Works
Wine (32bit):
League of Legends -- Always crash
World of Warcraft 1.21 -- Always crash
World of Warcraft 2.4.3 -- Sometimes crashes
World of Warcraft 3.3.5 -- Most times works
