Bug 8842 – Error line numbers for some run-time functions in debug mode?

void main() { int[] foo; auto bar = new int[10]; foo[] = bar[]; } Currently that code gives a runtime error with no line number, dmd 2.061alpha: object.Error: lengths don't match for array copy The stack trace helps find the location of such error, but maybe in debug mode (-debug) it's worth using a different _d_arraycopy run-time function that accepts line numbers too (named _d_arraycopy_line or something), so it's able to generate a more specific error message. This line number inflates the binary, but in debug mode what's important is to locate the errors very well.

It looks like it was a long journey for the compiler, but since 2.075 the line number is being printed (for -g builds), and is even printed correctly since 2.078.
