[Bug tree-optimization/34123] New: [4.3 Regression] verify_ssa failed (definition in block 11 does not dominate use in block 7)

["tbm at cyrius dot com" <gcc-bugzilla at gcc dot gnu dot org>]

With current trunk:

(sid)tbm@coconut0:~$ /usr/lib/gcc-snapshot/bin/gcc -c -O -ftree-loop-linear
md2.c
md2.c: In function 'MD2Transform':
md2.c:6: error: definition in block 11 does not dominate use in block 7
for SSA_NAME: t_20 in statement:
t_10 = PHI <t_20(7), 0(2)>
PHI argument
t_20
for PHI node
t_10 = PHI <t_20(7), 0(2)>
md2.c:6: internal compiler error: verify_ssa failed
Please submit a full bug report,

I originally thought this was the same as PR31037 and didn't file a PR
but the other testcases work now while this one still fails.
