Re: Unchecked_Deallocation and Constraint_Error

["Marin David Condic" <dont.bother.mcondic.auntie.spam@[acm.org>]

It is probably really important to know the platform, compiler, version and
compiler options enabled when discussing why an exception of this nature is
or is not raised. I could easily imagine a compiler optimizing away the
checks necessary for this exception in the abscence of options specifying
full Ada95 runtime checking.

I know, for example, that Gnat won't generate the checks that cause
Constraint_Error on integer range excptions unless you throw a switch to
enable it. Could this be a similar case?
