------- Comment #3 from hubicka at gcc dot gnu dot org 2008-01-20 11:56 -------
Double checking patch, I don't see obvious mistakes. Since the patch should
only affect register allocation decisions, either we see a latent bug, or
another example of x86 extra precision causing FP program to misbehave. I used
to have LD_PRELOAD library to set 64bit precision that often helped, I will
check this.
