>From g-trasym.ads:

"On all platforms except VMS, this package is not intended to be used
within a shared library, symbolic tracebacks are only supported for the
main executable and not for shared libraries. You should consider using
gdb to obtain symbolic traceback in such cases."

This reads to me: don't use in a shared library. Maybe they just followed
this advice. I admit, I don't understand the text above. In particular,
since any library is dead without the main executable, comparing them makes
no sense to me.
