I have looked into this problem, and found calling af_local_set_secret()
in fhandler_socket_local::bind() causes exception 0xc0000005.
Calling RtlGenRandom() in af_local_set_secret() may not be as expected.
While building cygwin1.dll in 32 bit environment, following warning is
shown. This is probably the cause.
Warning: resolving _SystemFunction036 by linking to _SystemFunction036@8
I am not sure why, but the following patch seems to be able solve this
problem.
