I just tried to compile Fortran package LAPACK with the
GNU Fortran compiler version 4.3 snapshot 20070525
The compiler said
/home/dcb/gcc/20070525/results/bin/gfortran -g -O3 -Wall -c clanht.f -o
clanht.o
clanht.f: In function 'clanht':
clanht.f:1: error: found a virtual definition for a GIMPLE register
PHI argument
D.1410_62
for PHI node
e__I_lsm0.52_95 = PHI <D.1410_62(21), e__I_lsm0.52_94(25)>
clanht.f:1: internal compiler error: verify_ssa failed
Please submit a full bug report,
with preprocessed source if appropriate.

Source code attached. Flag -O3 required.
