I just checked. Exception _does_ take a default file and line number.
Huh, maybe my dmd is getting old.
Maybe we should revisit this after the next dmd release. Sounds like
one is coming pretty soon with a lot of yummy goodness in it. All
of this Exception stuff may be moot.
It was in dmd 2.052. I don't know when the change was made though. I
might have been the one to change it too. I made several changes a while
back to make it so that Exception and Error types had default file and
line numbers (and I actually had to remove several on various Errors,
because the way that they're actually created makes them not work with
default arguments).

Ok
It would nice to have file and line info available on Mac OS X as well.
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.

Ok, I see that I was quite unclear. File and line info are available
when an exception is thrown but not in the stack trace. If the stack
trace uses the debug info then the problem is that the debug info
segments are incorrectly named on Mac OS X.
