Howdy,
there is a recent regression which shows up in the
attached code which is stripped down from LAPACK's
dlasv2.f
% gfc --version
GNU Fortran 95 (GCC) 4.2.0 20060323 (experimental)
% gfc -c dlasv2.f -O
dlasv2.f: In function 'dlasv2':
dlasv2.f:3: error: missing definition
for SSA_NAME: t_35 in statement:
D.922_38 = t_35 + mm_36;
dlasv2.f:3: internal compiler error: verify_ssa failed
Interestingly, the ICE does *NOT* show up when
enabling -ffast-math, commenting out the marked line
in the code or playing around with the IF constructs.
Cheers,
-ha
