Present on SPARC/Solaris too. It's a bug in the runtime.

well, LAST_UPDATED: Fri Sep 16 15:58:15 UTC 2005, and on

The stack is trashed because a routine of the runtime writes one byte past the
end of the slot it is passed. Recompile the runtime without -gnatp and you will
see a nice CONSTRAINT_ERROR.

Only a quick fix that doesn't solve all the cases. Geert is the specialist here.
