I wasn't talking about memory required to create the array.  The array
isn't created by cc1, it is the linker which does it.  cc1 only needs
to parse the source, it does not allocate the space for the variables
it parses.

My testing indicates (see my other mail in this thread) that cc1
indeed uses malloc'ed storage, not the stack space, and that it's
probably the parse tree build process that's responsible for the
outrageous memory usage.

It might be because of the DPMI server you are using.  I tested under
CWSDPMI and Windows 95, and only saw "out of virtual memory" messages
under CWSDPMI (Windows 95 just paged, but let the compiler finish).
