re PR tree-optimization/34093 (ICE in ssa_operand_alloc, at tree-ssa-operands.c:484)
2008-01-02 Richard Guenther <rguenther@suse.de>
PR middle-end/34093
PR middle-end/31976
* tree-ssa-operands.c (ssa_operand_alloc): Also allocate a buffer
for very large number of operands instead of ICEing.
* gcc.c-torture/compile/pr34093.c: New testcase.
