I tried to compile gsl-1.5 with the actual snapshot of gcc40 and got an ICE 
when I use -ffast-math.

: Search converges between 2004-10-09-014001-trunk (#585) and 2004-10-09-161001-trunk 
(#586).

Reduced testcase:
extern int isnan (double __value) __attribute__ ((__const__));
int
gsl_isnan (const double x)
{
  return isnan(x);
}

Confirmed.
