--- Comment #4 from Kenji Hara <k.hara...@gmail.com> ---
This is a mangling scheme issue and function symbol is confused in link stage.
module test;
extern(C) int printf(const char*, ...);
enum Method { A, B, }
void foo(Method method = Method.A)()
{
pragma(msg, "1: ", foo.mangleof);
foo!method();
}
void foo(Method method : Method.A)()
{
pragma(msg, "2: ", foo.mangleof);
}
void main()
{
foo();
}
foo() instantiates the first version `void foo(Method method = Method.A)()`,
then it instantiates the second version `void foo(Method method : Method.A)()`.
But the instantiated two functions have exactly same mangled names, so the
pragmas print:
1: _D4test24__T3fooVE4test6Methodi1Z3fooFZv
2: _D4test24__T3fooVE4test6Methodi1Z3fooFZv
and the foo!method() wrongly call itself.
