We are doing a medium-scale software project for a class.  The C compiler
with debug options set takes about 350k, and our code occupies about 160k.
There is enough memory to run the program, but not in the interactive
debugging mode (which is very helpful for tricky bugs, like when the whole
system just 'locks up'.)
