Hi everybody,
I'm experencing an odd error on a double processor machine.
The same source code compiles well on all boxes I used but on a single
machine it fails.
It's the only 2-processor box I use. That's why I assume the problem is
some weird concurrency issue but I'm not sure.
When I try to compile it a couple of times in a row sometimes
compilation works, sometimes it fails and it's really abitrary.
Here's the error message:

Is that a known issue? Some flags or cygwin variable I can set to
prevent that?
It's a WinXP box, gcc 3.4.3, CYGWIN_NT-5.1 1.5.16(0.128/4/2).
Thanks in advane for any suggestions or help.
