It's generally done by parsing the contents of a detailed MAP file which was
generated along with your project's EXE and matching that against the
Exception Addr. Once you've got the parsing sorted out, you can also do
things backchain through the Call Stack to give a stack trace which you can
log into an diagnostics file. This can be very handy to determine what
_really_ caused that obscure exception out in the field.
Anyway, .MAP file parsing is what I did to add this and File/Line/Proc
Asserts to my code back in the Delphi 2 days.
