Re: Function returning "Boolean" in a binding

["Marc A. Criley" <mcquad2@earthlink.net>]

Yes, "Internal bug" would not be a sanctioned GNAT error message for
this situation.  You ought to send a bug report to report@gnat.com
describing exactly what you saw, and if possible providing a standalone
program that demonstrates the problem.

When you got the "Internal bug" message you were informed of this via a
GNAT "bug box", yes?  Just follow the directions it displays.
