--- Comment #4 from Dominique d'Humieres <dominiq at lps dot ens.fr> --- > As the status "accidentally fixed in 4.8 but do not know when and why" > does not exist, you may well do that. I get the SIGFPE with revision 192891 (2012-10-28) and 'In p_h_usstd!' with revision 193261 (2012-11-06) and newer. Note that since the SIGFPE needs -O1, it may have been fixed in the middle-end. But if you really want to find out, you'll have to do the remaining bisection yourself. BTW in comment #2 I ment '-O1 -ffpe-trap=zero,overflow,invalid -finit-real=snan -mfpmath=387'.
