Hi Corinna,
Tested up to
http://cygwin.com/ml/cygwin-cvs/2012-q2/msg00129.html
There are no exceptions on the strace.
The last portion, ~ 500 lines, of strace is available here:
http://matzeri.altervista.org/works/atlas/
together with the equivalent area of the good strace (~ 1000 lines).
A normal exception should kill just the running process, while
I see that xprobe_comp, bash, mintty are killed and
also others bash and mintty processes are taking down.
Regards
Marco
