Subject:	Failure with fork()
From:	Arjen Markus <arjen DOT markus895 AT gmail DOT com>

Hello,

the bug I am reporting here on behalf of Alan Irwin surfaced in the
combination wine and Cygwin (Alan summarised it here:
http://www.winehq.org/pipermail/wine-devel/2013-June/100328.html). It
has to do with the way Cygwin handles forks.

The bug can be illustrated with this small program:

int main(void) {
    while(!fork());
    return 0;
}

It is meant to enable infinite forking, but on Cygwin it immediately
stops. I tried
it on both Cygwin (not via wine but simply Windows 7) and Linux:
- On Linux the program continues without any problem
- On Cygwin it stops immediately with an error message that the child process
  terminated unexpectedly with some weird return code.

Can anyone shed light on this? This bug is a showstopper for the
combination wine
and Cygwin.

Regards,

Arjen
