Following up on your problems with TurboC++, I too have had the same problems.
The application which I have been involved in developing is currently
about 10K lines of my own source code not considering the class library
and include files.   The class hierarchy which I have developed
is approximately 7 levels deep at the greatest.

I was using a lot of inline code in my low level class definitions
to improve performance, and it was this that was causing me
a great deal of memory problems.  When I reduced the inline code to
only the most minimal situations, the memory problems went away.

Apparently, using inline code requires a significant amount of
RAM to hang on to, and it does not take a whole lot of code
to use up all available space.

Hope this helps some.
