I can't reproduce it on x86_64. reading all the comments in the gcc bug report, this is because x86 targets the x87 fpu by default which is where the bug is -- it's a hardware problem. x86_64 targets sse which has stricter standards for rounding. most x86 processors support sse -- is there a reason why we don't target sse? merlin
