Whether there is file and line info with an exception should have nothing to do with the OS, except perhaps in some low-level stuff that druntime does, but I don't think that it makes a difference even then. Pretty much anything and everything derived from Exception should give a file and line number - generally that file and line number are the point where the exception was thrown from. Many Errors _can't_ have proper file and line numbers due to how they're thrown, though some of them (such as AssertError) should have proper file and line numbers. So, I don't know why you wouldn't be seeing file and line numbers on Mac OS X. It should be the same as the other OSes. Stack traces are another issue (and I have no idea if Mac OS X currenly has them), but the behavior with regards to file and line numbers in exceptions should be the same for all OSes. I don't know why they wouldn't be. - Jonathan M Davis
