This loop does not make progress for me. I don't see the out-of-bound
access immediately.
But if you build 416.gamess with -O -fbounds-check you immediately get
Running 416.gamess ref base amd64-m64-gcc42-nn default
/abuild/rguenther/spec2k6/bin/specinvoke -d
/abuild/rguenther/spec2k6/benchspec/CPU2006/416.gamess/run/run_base_ref_amd64-m64-gcc42-nn.0001
-e speccmds.err -o speccmds.stdout -f speccmds.cmd -C
416.gamess: copy #0 non-zero return code (rc=2, signal=0)

which is not within the offending accesses. Manually just compiling
prppop.F with -fbounds-check reveals

thus, similar.
