Anyone knows this issue? std/math.d(2759): Error: number '0x1p-1024' is not representable

I'm getting this error while trying to build the relase.

std/math.d(2759): Error: number '0x1p-1024' is not representable

I'm getting that while compiling a -m32 (X86) static release phobos
library, but I can't reproduce the error using the same command.

Don't even know why the unittests are compiled.
