Yes.

First step, please test with the latest Cygwin developers snapshot,
if the problem persists.  See http://cygwin.com/snapshots/

If yes, send a *minimal* testcase to reproduce the problem.  Minimal
testcase means a short, concise source code, possibly written in
pure C, which is compilable out of the box, with not more than the
necessary lines of code to reproduce the effect.
