I think I didn't use it with Gnat 3.13p and read somewhere that it is not
required.
But since Traceback doesn't work with Gnat 3.14 p , I followed what the Gnat
user's guide says (without success ...)

-E
Store tracebacks in exception occurrences when the target supports it. This
is the default with the zero cost exception mechanism. This option is
currently only supported on Solaris, Linux and Windows ix86. Under Solaris
and Linux you need to use explicitly the gcc flag -funwind-tables when
compiling every file in your application. See also the packages
GNAT.Traceback and GNAT.Traceback.Symbolic. Under Windows there is no
specific option to use to enable this feature but you must not
use -fomit-frame-pointer gcc option.
