Bootstrap failure -- verify_ssa failed

[Ulrich Weigand]

Hello,

with current GCC mainline bootstrap fails on s390(x)-ibm-linux
during stage2 build with:

../../gcc-head/gcc/tree-ssa-operands.c: In function 'finalize_ssa_uses':
../../gcc-head/gcc/tree-ssa-operands.c:570: error: Definition in block 64 does not dominate use in block 13
for SSA_NAME: TMT.628_22 in statement:
TMT.628_41 = PHI <TMT.628_22(13), TMT.628_389(107)>;
PHI argument
TMT.628_22
for PHI node
TMT.628_41 = PHI <TMT.628_22(13), TMT.628_389(107)>;
../../gcc-head/gcc/tree-ssa-operands.c:570: internal compiler error: verify_ssa failed.

Before I start debugging, does this ring any bells?

Thanks,
Ulrich
