I am not using Cygwin - could not even find that DLL on my computer.
I think gnatmem is confused there. Also, the gnatmem output did show alot
of DEALLOC messages for unbounded_string's (along with the ALLOC's).

There are 3 major areas where I use unbounded_string's in the pgm. I 
changed to fixed strings in one area, and have not seen memory 
problems there any more. I really like the unbounded variety, but 
can not have the program crashing all the time. 

I used to run it more on Unix (Rational Ada) and only on Gnat for 
development. And did not have these problems. But this version is Gnat only. 
(Using Gnat Sockets). I have made other changes too. But the messaging
means more exercising of the Unbounded_String objects I have, and it 
seems to be the cause of the memory problems.

From the RM, it sounds like Bounded_String's would be as bad. It said
they should not be dynamically allocated. 

Hey. Could it be that the Unbounded_String's are not the problem per se, 
but the fact that they are within record objects being dynamically
allocated is the problem?  Or one of the problems?

thanks,
