The following invalid code snippet is accepted since GCC 3.4.0:
=========================================
template<int> struct A {};
template<typename> struct B : A<sizeof(0=0)> {};
=========================================
Before the code was correctly rejected, although the error message
couldn't be printed:
bug.cc:3: sorry, unimplemented: `modop_expr' not supported by dump_expr
bug.cc:3: sorry, unimplemented: `modop_expr' not supported by dump_expr
