gcc claims to be IEEE compliant at all level of optimizations (-O*):
Sets -fno-math-errno, -funsafe-math-optimizations,
-fno-trapping-math, -ffinite-math-only, -fno-rounding-math,
-fno-signaling-nans and fcx-limited-range.
This option causes the preprocessor macro "__FAST_MATH__" to
This option should never be turned on by any -O option since
it can result in incorrect output for programs which depend on an exact
implementation of IEEE or ISO rules/specifications for math functions.
So I don't think that's the problem.
