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

I'm getting the following ICE with gcc 4.3 20060515 and -O3:

(sid)24074:tbm@em64t: ~/delta/bin] /usr/lib/gcc-snapshot/bin/gcc -c -O3 838.c
838.c: In function 'rPIc_entry':
838.c:3181: internal compiler error: in ssa_operand_alloc, at
tree-ssa-operands.c:487
Please submit a full bug report, ...

I'm currently reducing it.  I'll attach a testcase later.
