[Bug fortran/32635] New: gfortran - internal compiler error: verify_ssa failed

[dir at lanl dot gov]

This error poped up while trying to recompile one of my programs. I have
reduced it about as much as I could - change almost anything and the error goes
away -

[dranta:~/junk] dir% gfortran -c -O2 aled7.F
aled7.F: In function 'aled7':
aled7.F:1: error: definition in block 6 follows the use
for SSA_NAME: D.1023_61 in statement:
D.1017_52 = D.1023_61;
aled7.F:1: internal compiler error: verify_ssa failed
Please submit a full bug report,
with preprocessed source if appropriate.
