How to debug?

[Marius Amado Alves <maa@liacc.up.pt>]

How do I inspect the call stack (preferably symbolic information i.e. source 
code unit name + line number + subprogram names), upon an unhandled exception 
occurrence?

I'm on Windows XP, with GNAT 3.15p. I tried GVD and gdb to no avail (yes, 
compiled with the -g option). Would it work on Linux?

Do I have to catch the exception, perhaps just to put a breakpoint in the 
handler?

Sometime ago, I think with GNAT 3.13p or 3.14p, I also tried instrumenting my 
code with GNAT's Symbolic_Traceback but it also didn't work. Would it work 
now with version 3.15p?

Would GPS do the trick?

Thanks a lot.

/* So far I seem to have been able to produce working Ada programs without a 
debugger. I instrument. But now I'm tired. And it's rather irritating that 
Ada, GNAT, the 'p' versions, does not facilitate debugging like e.g. the 
Borland products did. I miss that aspect of them. I whish there was a Turbo 
Ada. */
