Hi,

Is this a bug in the compiler?

Attempting to compile with a recent dmd git head causes segmentation 
fault. Any compiler crash is a compiler bug. Please report it at

A first reduction for Bugzilla:


alias TypeTuple(T...) = T;
struct A {
     void foo() {}
}
template ItemProperty(item, string method) {
     static if(__traits(getProtection, ItemProperty!(item, 
method)).stringof)
         alias ItemProperty = TypeTuple!(ItemProperty!(item, 
method));
}
void main() {
     auto l = ItemProperty!(A, "foo").length;
}


Bye,

Thanks for the code revised version. I thought that the compiler 
crashes because I was trying to get the access of an overrided 
method.
