524 – Compiler crash when compiling

boost::any implementation in d has a bad luck... It was already not linking when compiling as separate files (bug #384), and in 0.174 compiler just crashes when trying to compile it... Binary is not produced. I could not gather much more info than above, so I attache test files.

Created attachment 50 [details] 
Trying to compile attachment makes compiler crashing...

After some testing it occurred that this regression was introduced in 0.173. 0.172 works fine.

I think that this bug is caused in nested template class.
I made simple testcase:
static class Test{
 void test(T)() {
 new Inner!(T)();
 }
 class Inner(T) {
 void test(){ new Inner!(T)();}//maybe this is causing infinite loop
 }
}
void test(T)(){new Test2!(T)();}
class Test2(T) {
 void test(){ new Test2!(T)();}
}
void main(){
 test!(int);//ok
 (new Test).test!(int);//crash
}

Fixed in DMD 0.176.
