[Bug c++/22071] New: 4.1 regression: ICE in first_vi_for_offset, at tree-ssa-structalias.c:2506

["zlynx at acm dot org" <gcc-bugzilla at gcc dot gnu dot org>]

# g++ -O /tmp/j1.cc
adaptors/lambda/lambda.cc: In function 'void
__static_initialization_and_destruction_0(int, int)':
adaptors/lambda/lambda.cc:15: internal compiler error: in first_vi_for_offset,
at tree-ssa-structalias.c:2506

j1.cc will be attached.
-O is what triggers the ICE.  Compiling without optimization works.

# g++ -v
