The following invalid code snippet is accepted since at least GCC 2.95.3:
============================
typedef int operator! ();
============================
With such a broken declaration it's easy to crash the compiler afterwards:
============================
struct A {};
typedef int operator! (A);
int i = !A();
============================
bug.cc:3: error: argument dependent lookup finds 'operator!'
bug.cc:5: error: in call to 'operator!'
bug.cc:5: internal compiler error: tree check: expected function_type or
method_type, have error_mark in add_function_candidate, at cp/call.c:1327
Please submit a full bug report, [etc.]
