has broken.
$ /home/dcb/gcc/results/bin/gcc -c -O2 -w /home/dcb/gcc/foundBugs/bug647.c
auprocess.c: In function ‘rcm_1’:
auprocess.c:1275:17: error: stmt with wrong VUSE
# VUSE <.MEM_34(D)>
n_39 = el_35(D)->nextSample;
expected .MEM_33
during GIMPLE pass: sink
auprocess.c:1275:17: internal compiler error: verify_ssa failed
0xf02e86 verify_ssa(bool, bool)
../../trunk.git/gcc/tree-ssa.c:1208

../../trunk.git/gcc/passes.c:1999
0xbcc211 execute_todo(unsigned int)

I'll have a go at reducing the code.
