Dear Simon,
Our problem is that we don't get a traceback at all.
In AdaCore's GNAT the traceback is displayed by default in hex.
To convert that into a symbolic traceback we use Gnat.Traceback.Symbolic.
However this is not the problem.
The problem is that we don't get a traceback at all - ie the -E switch doesn't seem to have the desired effect.
In System.ads ZCX_By_Default is set to False for AdaCore GNAT and True for TDM so I wondered if that had anything to do with the problem.
However John seems to think that the problem is more fundamental.

MfG
