[gtkada] crash when displaying opengl area

I've also heard about problems with the gnat version that
comes with Red Hat 9.0. And someone who compiled my program
with that latest version under a Russian Linux distribution
got a gnat bug detected.
So I'd suggest trying gnat 3.15p. with gcc 2.8.1.
Glad it's stable with gcc 3.2 on the Mac!
