   Summary: Parse error involving "templated method inside
templated class"
   Product: gcc

Status: UNCONFIRMED
  Severity: normal
  Priority: P3
 Component: c++

Compiler invocation: "g++ -ftemplate-depth-128 -O0 -fno-inline -Wall -g -c -o

I have attached (and pasted) reduced code that exhibit the behavior, with

static void from_method(T *object_ptr) {}
};

template
struct Event {
typedef Delegate DelegateType; // REMOVE  TO REMOVE PROBLEM

template 
void connect_method(T *object_ptr) {
// The following line fails with:
// buggy.cpp:16:36: error: expected primary-expression before '>' token
DelegateType::from_method(object_ptr);
}
};

int main(int argc, char *argv[]) {
return 0;
}
