[Bug c++/27115] [4.0/4.1/4.2 Regression] ICE in cp_expr_size or miscompilation

[reichelt at gcc dot gnu dot org]

Confirmed.
Shorter testcase that crashes at -O0:

================================
struct A
{
    A (const A&);
    A& operator= (const A&);
};

void foo(A a)
{
    A b = ({ a; });
}
================================

bug.cc: In function 'void foo(A)':
bug.cc:9: internal compiler error: in cp_expr_size, at cp/cp-objcp-common.c:101
Please submit a full bug report, [etc.]

The problem seems to be the statement-expression.
Just initializing "A b = a;" makes the ICE go away.
