digitalmars.D.bugs - lazy in main

reply Carlos Santander <csantander619 gmail.com> writes:
This compiles successfully:

int main (lazy char [][] args)
{
         return args.length;
}

But at runtime I get "Illegal instruction". Tested with gdc from SVN repos
(uses 
dmd 0.166) on Mac OS X.

I would call this a bug in the compiler. The spec states there are only 
four valid forms of main:

void main() { ... }
void main(char[][] args) { ... }
int main() { ... }
int main(char[][] args) { ... }

Since that isn't one of them, I would think the compiler should issue an 
error.
