          Priority: P2

This code:

void main() {
    auto a1 = new int[5];
    auto a2 = new int[4];
    a1[] = a2;
}

Produces an error at runtime that doesn't show the line number (and file name): object.Exception: lengths don't match for array copy

Suggestion from Steven Schveighoffer: once a stacktrace printout is available, probably there is no need to instrument code like this to show line numbers.

I can't help you with lines (it would probably kill performance), but druntime already had some code to deal with mismatching lengths. It printed mismatched lengths for array assigns but not for copies (and also it printed invalid lengths due to relying on specific expression evaluation).

I'm fixing this now.
