You need to build with -g (debug info) and -bargs -E (-Es?) for this to
work well.

If you're on a Mac, you'd see something like (this is from a demo
program of mine)

   $ ./raiser

   Execution of ./raiser terminated by unhandled exception
   raised PROGRAM_ERROR : raiser.adb:3 explicit raise
   Load address: 0x10cb10000
   Call stack traceback locations:
   0x10cb11163 0x10cb11104

and you get the traceback by

   $ atos -o raiser -l 0x10cb10000 0x10cb11163 0x10cb11104
   _ada_raiser (in raiser) (raiser.adb:3)
   main (in raiser) (b~raiser.adb:158)

where the -l part is the Load address - programs are loaded at random
addresses to defeat some hacking vulnerabilities.
