1.5.25: Segmentation fault on Window, x64, running on VMware

["Christoph Jeksa" <Christoph_Jeksa at CoCreate dot com>]

This is a problem in using of Cygwin-tools on Windows x64, running on VMware.

I'm using Cygwin 1.5.25 on a Windows 2003 Server, 64-bit Standard Edition running on VMware Workstation ACE Edition, Version 6.0.2. The host system is a Windows 2003 Server R2 Enterprise x64 Edition, SP2, running on Intel Xeon CPU Dual Quad Processor X5355, 32 GB Memory.

In that environment, different Cygwin-tools (grep, mkdir, etc.) break OCCASIONALLY with the state "Segmentation fault (core dumped)". Please find below the test case to reproduce the error state:

$ while mkdir foo; rmdir foo; do
>   :
> done

During my tests, the while-loop ran a while and has broken with the error message: 
13 [main] rmdir 2364 _cygtls::handle_exceptions: Error while dumping state (probably corrupted stack)
Segmentation fault (core dumped)

In an another trial I've got an another errors:
mkdir: cannot create directory `foo': File exists
     10 [main] mkdir 780 _cygtls::handle_exceptions: Error while dumping state (probably corrupted stack)
Segmentation fault (core dumped)
rmdir: failed to remove `foo': No such file or directory

... and so on.

Below, the stack dumps from the last trial:

mkdir.exe.stackdump:

the same version of Cygwin and Cygwin-tools works fine, when running on a "normal" (physical) x64 Windows system.
