[Bug tree-optimization/22488] New: ICE: in first_vi_for_offset, at tree-ssa-structalias.c:2585 with -O3

[micis at gmx dot de]

When I compile ace542 with the actual snapshot of gcc41 I get an ICE when I 
use -O3.

The last snapshot which works is gcc-4.1-20050604,
the first that fails is gcc-4.1-20050611
