Control: severity -1 serious I was recommended by multiple people to bump the severity of this bug. Also to clarify that i386 should have no optimisation flags, and not "-msse -msse2". My earlier comment was based on a misunderstanding of what "i386 doesn't have mmx" meant; sse and sse2 build on top of mmx.
