Yet another ICE in first_vi_for_offset. Compile the following code snippet
with "g++ -O":
=========================
struct A { A(); };
struct B : A
{
A a;
};
struct C : B { };
C c;
=========================
bug.cc: In function 'void __static_initialization_and_destruction_0(int, int)':
bug.cc:10: internal compiler error: in first_vi_for_offset, at
tree-ssa-structalias.c:2829
Please submit a full bug report, [etc.]
Probably different from PR22277, since I can trigger PR22277 with a 20050709
snapshot, but not the one above (which I can trigger since 20050710).
Actually the problem seems to be related to PR22071.
