The C++ frontend generates a broken diagnostic for the following code snippet since GCC 3.4.0: ============================================== template<int> void foo(int(*f=0)()); ============================================== bug.cc:1: error: variable or field 'foo' declared void bug.cc:1: error: 'f' was not declared in this scope bug.cc:1: error: '(int)(#'modop_expr' not supported by dump_expr#<expression error>)' cannot be used as a function Another testcase for the unsupported 'modop_expr' is the following: ============================================== template<int> struct A { int i; typeof(A = A()) i; }; ============================================== bug.cc:2: error: expected primary-expression before '=' token bug.cc:2: error: declaration of '__typeof__ (#'modop_expr' not supported by dump_expr#<expression error>) A<<anonymous> >::i' bug.cc:1: error: conflicts with previous declaration 'int A<<anonymous> >::i'
On it.
