GNAT.Traceback is back...

GNAT.Traceback is back...

[Gautier]

Hi all.

Some mysteries around GNAT.Traceback in GNAT 3.12p for Win32 are not
resolved.

 1) Does GNAT.Traceback really work on GNAT 3.12p for Win32 ?
    We know that the .Symbolic child works only for Linux and Solaris,
    as stated in the user's guide. Yes, I've built with the options
    "gnatmake -funwind-tables -g tractest -bargs -E", but all I
    obtain is 0 callback levels (like Christophe Gouiran in his post
    about that) !

 2) Assume I could obtain more than 0 levels, but I don't
    have a working package to transform addresses into names.
    How to do it by calling gdb ? Is there a gdb command for that ?

 3) Will GNAT 3.13p bring symbolic call-backs for Win32 ?

Below is an expanded version of Christophe's example.
Ironically I obtain 2 levels & addresses in GNAT 3.12p for DOS...

         raise; -- -> output exception name & co
      end;

end Tractest;

No, it is not implemented under Win32 on GNAT 3.12p.

Yes.
