Confirmed on powerpc-apple-darwin9 and x86_64-apple-darwin10 with revision
183181. Revision 183001 is OK. The ICE is also triggered with '-O1
-finline-small-functions -finline-functions -fipa-pta -fpartial-inlining' up to
'-O3 -fipa-pta'. If I set a break point for insert_vi_for_tree, I see it
called several time before reaching:
Breakpoint 1, insert_vi_for_tree (t=<value optimized out>, vi=<value optimized
out>) at ../../work/gcc/tree-ssa-structalias.c:2639
2639 {
