[Bug fortran/39314] -ffpe-trap=invalid gives no FPE for acos(-5.0)



------- Comment #3 from burnus at gcc dot gnu dot org  2009-02-26 18:03 -------
Confirm: Here, I get the same result with -m64 on Linux (NaN and no SIGFPE),
but with -m32 (with both -mfpmath=sse and -mfpmath=387) I get the SIGFPE.

The FPE settings are used in libgfortran/config/*; maybe fpu-387.h does
something wrong in the x86-64 mode?
