It sounds like your program is doing extensive tasking and interprocessor
communication. Given that I'd put good money on the problem being a timing
problem (aka: race condition) that exists on *all* your environments. It just
shows up most regularly on the SunOS target with the new gnat because the
timing environment with that setup happens to be just right.

Given that, it would definitely be worth your while to install the new gnat
and debug it there. The bug won't go away just becuase you wish it to.
Believe me, I've tried wishing. :-)
