The Nighthawk Ada83 compiler deallocated into its own program-wide pool of
memory, which would not ever be given back to the *system* until program
termination. Out of the 9 or so Ada compilers I have worked with, that's the
only one I know that might qualify. (Unless you count the Alsys SMART
compilers, which couldn't allocate either.)
