How much memory, overall, did you allocate?  Is it possible that you
have used up all the conventional memory?

What, if any, are the differences between the code in functions that
work and in the one that doesn't?  Do you ask for the same size, for
example?

It is also possible that, due to some unrelated bug, your code
overwrites the _go32_dpmi_seginfo structure, so the function gets it
garbled.
