BUG: cygwin-1.3.3+: Using ASH to executing .com files -- causes Invalid Page Fault

[Timothy Lee]

Since upgrading from cygwin-1.3.2, I've noticed that "sh" always causes 
Invalid Page Fault when executing .com files.

The crash is 100% reproduceable on difference machines running Win98 and 
cygwin 1.3.3 or higher:

    C:\windows>sh
    $more.com /?

At this point, a IPF will be generated, with the dialog box titled "SH", 
and the content:

    SH caused an invalid page fault in
    module KERNEL32.DLL at 016f:bff7d833.
    Registers:

    8175a700 61060574

This problem does not occur for cygwin-1.3.2.

I've attached the output ot cygcheck for the two different 
configurations.  Only the cygwin package is installed differently.

If this problem is related to mis-configuration of my computer, thanks 
in advance for any tips available!
