Most (all of the ones that _I've_ seen) of the Ada compilers will lose
track of the memory if you don't call unchecked deallocation. This was
a bad enough problem for us that I wrote a tool named plumber to help
find such leaks. For each block that is lost, it will log the call
stack from where the block was created. Reading the the stack frames,
involves some sparc-specific (SunOS) code. It works with any
combination of C and SunAda code. Plumber is also tasking safe.

Hope it helps,
