line numbers for linux exception traces

[Adam D. Ruppe via Digitalmars-d-announce]

Oh also a note about addr2line's output on my computer at least: 
it prints the line of the *next* instruction after the function 
call, which can be a few lines away sometimes.

But still, close enough: go to the line it references then look 
immediately before it and you should see the function call 
referred to in the stack trace.
