Bug Report

CWSDPMI returns incorrect available memory value - page faults when used

Summary:

On large memory machines (>256Mb) CWSDPMI will page fault when using 
memory which should be valid.  This is typically seen when paging is
disabled (or limited to a small size) and the program is trying to use
all of the physical memory.  Small changes in configuration (from raw
to XMS) may make the problem disappear.


Analysis:

It appears CWSDPMI is computing a size or offset incorrectly.  I've
been able to reproduce the problem, but I don't know the exact cause
or how to fix it yet.  Its a bad bug since a program may ask CWSDPMI
how much memory is available, then allocate it, then fail when using
it.


Workarounds:

Provide a larger swap file.
