[Issue 13485] FP wrong-code with -O

--- Comment #2 from Iain Buclaw <ibuclaw at gdcproject.org> ---
FYI, this looks more like an x87 problem, rather than compiler.  And it's not
just D that is affected by this.

For instance, this bug in gcc:

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=323


Though they did eventually fix it in implementing C99-conformant (kinda) excess
precision.
