The following testcase causes an ICE since GCC 3.4.0:
===================================
struct A
{
A& operator= (const A&) !;
};
struct B : A {};
void foo(B b)
{
b=b;
}
===================================
bug.cc:3: error: expected ';' before '!' token
bug.cc: In member function 'B& B::operator=(const B&)':
bug.cc:6: internal compiler error: Segmentation fault
Please submit a full bug report, [etc.]
Related to PR27379, but only happens with inheritance and doesn't crash
GCC 3.0.x.
