Hi,

I have problem with malloc hanging when I SwitchToFiber. I have current 
environment:
 
CYGWIN_NT-6.1 win7-dev 1.7.27(0.271/5/3) 2013-12-09 11:54 x86_64 Cygwin 
(Windows 7, x64)

I am trying to use Windows Fibers API in cygwin environment. All is working 
fine, till the moment I call SwitchToFiber and then malloc. The processor CPU 
usage goes to 50% and after some time to 100%. In most cases this a result of 
memory corruption.  In case I do not call malloc, all is working fine. Is this 
something to do with the stack?

I made small test project attached to the email.
