State-Changed-Why:
Not a bug. On x86, when optimizing, floating point values
may be kept in FP registers when doing comparisons with
others stored in memory. Now x86 FP registers have
extra-precision over a 'double', which may invalid
a comparison. Compile your code with '-ffloat-store'
if it relies on exact IEEE floating-point semantics.
