grep (2.5.1) ACCESS violation bug

[Bacchu, Anjan]

Hi There,
 
    I can recreate a GPF(ACCESS violation) in grep(grep (GNU grep) 2.5.1)
on a custom redhat linux 2.4.x kernel on dell i386 hardware). 
pls. see below.
 
Also, I was able to recreate the same problem on my workstation
using cygwin's version of grep (again 2.5.1) -- pls. see DOWN BELOW.
 
Thank you,
 
BR,
