The error message when accessing a null reference of an object does not provide file and line number. void main() { Foo foo; foo.run(); } class Foo { void run() {} } The code above compiles and when run says: object.Error: Access Violation

Is the stack trace feature going to do this? To implement this I think the compiler has to add a pointer to the filename string and a line number to every call point to class methods, and more. So this can be done in nonrelease mode. In optimized builds this can be a drag.

We have stack traces for this now.
