[Bug c++/13772] New: [tree-ssa] ICE in get_expr_operands

[reichelt at gcc dot gnu dot org]

The following example causes an ICE when compiled with "g++ -O -c":

======================================================
struct A
{
    int i[2];

    int& operator[] (int j) { return i[j]; }

    int foo() { return (*this)[1]; }
};

void bar()
{
    A a[1];
    a[0].foo();
}
======================================================

The error message is:

ssa-bug.cc: In function `void bar()':
ssa-bug.cc:11: internal compiler error: in get_expr_operands, at
tree-ssa-operands.c:918
Please submit a full bug report, [etc.]

This is closely related to PR 13681, but here we don't have an
out-of-bounds access.
