I uses this approach and it works just fine. (DMD/Linux and IIRC DMD/Win)

I've never seen this.

  OTOH I don't actually catch the exception as the only thing I actually 
uses the exception for is a poor man's stack trace:

// add this at the top of all functions.
scope(failure) writef(">>"__FILE__":"~itoa!(__LINE__)~\n);
