Hi All,

I'm trying to write functions (library) for reading data and its description.

- When compiled under DOS (Turbo C) the result is unpredictable, so
  "something rotten is in the state of my code".
- Under OS/2 the program traps 0005 before anything is done, even the
  first executable statement is not executed. (PM debugger).
- Under Unix everything runs perfectly well.

As i am puzzled by this anomaly, i tried some more compilers. MS C tells me
that 'automatic data allocation exceeds 32k'. The reason for this message
is a struct, which is 40 kB in size.

When i changed:

   struct desc heads;

into:

   static struct desc heads;

problems are solved under OS/2 and DOS; the reason probably is that the
struct is placed in the data segment.

The same result (under OS/2 and DOS) could be achieved when static is
omitted when simultaneously the stack size was enlarged to STACK:50000.

I would appreciate if anyone could explain me why the stack is not
automatically chosen to be sufficiently large, or better how to
order the compiler to choose the right stack size. I'm using ibm's C
compiler, version 2.01.


Groeten,
 Henk
