The following valid code snippet is rejected since GCC 4.0.3.
On mainline it even triggers an ICE:
=========================================================
struct A
{
template<typename T> operator T() { return T(); }
};
template<int> void foo()
{
A().operator int();
}
void bar()
{
foo<0>();
}
=========================================================
bug.cc: In function 'void foo() [with int <anonymous> = 0]':
bug.cc:13: instantiated from here
bug.cc:8: error: invalid use of template type parameter
bug.cc: In member function 'A::operator T() [with T = T]':
bug.cc:8: instantiated from 'void foo() [with int <anonymous> = 0]'
bug.cc:13: instantiated from here
bug.cc:3: internal compiler error: in dependent_type_p, at cp/pt.c:12523
Please submit a full bug report, [etc.]
The code compiles fine, if I turn foo into a regular function.
