[Bug tree-optimization/22279] New: [4.1 Regression] ICE in first_vi_for_offset, at tree-ssa-structalias.c:2566

[jsm28 at gcc dot gnu dot org]

On various platforms, the libstdc++ testsuite fails early with an ICE building
testsuite_abi.cc.  This includes at least hppa64-hpux and ia64-hpux (compilers
as of 20050702 07:00 UTC) and gcc-testresults shows it on x86_64-linux; it
didn't happen with 20050630 compilers.  The dates show this is a different bug
from bug 22071.
