A bug in the Cygwin DLL (64-bit only) was just discovered and fixed. 
The bug could have prevented stack space from being committed after the 
initial commit.  Could you try the latest snapshot from 
https://cygwin.com/snapshots/ and see if these strange crashes stop?  I 
realize that you may have to run emacs for several weeks before you can 
be confident.
