This small program is just a tiny part of a huge application, which is 
built natively on Windows, and intended to be run without Cygwin by the 
customers.
However we in development use Cygwin extensively, mostly to use the same 
scripts/environment as on Unix platforms (where our application is also 
built).
Hence your suggestion to use mingw is not applicable in our case. Out 
application is not cygwin-aware.

Still something does not look right to me:

(1) Even if cygwin has its own exception handling, how is it possible 
that it interferes with exception handling in my program (which is a 
separate process) ?

(2) Why this issue is not reproducible when cygwin shell is started in a 
regular (cmd?) window, but reproducible only in rxvt/xterm window?

BTW, I've tried running this program under bash, tcsh, and sh, and the 
behavior is the same - that is, the shell is not relevant to this 
problem, only window type is relevant.

It looks like a rxvt/xterm-specific issue.

I wonder if somebody can take a look at it...

Thanks,
Alex
