[Bug fortran/32194] New: ice for legal code with -O3

["dcb314 at hotmail dot com" <gcc-bugzilla at gcc dot gnu dot org>]

I just tried to compile Fortran package LAPACK with the
GNU Fortran compiler version 4.3 snapshot 20070601

The compiler said

/home/dcb/gcc/20070601/results/bin/gfortran -g -O3 -Wall -c zlag2c.f -o
zlag2c.o
zlag2c.f: In function 'zlag2c':
zlag2c.f:85: internal compiler error: in convert_move, at expr.c:361
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.

Source code attached. It compiles ok at -O2, so flag -O3 required.
