Your cygcheck output shows that you're not using the latest version of 
rebase.  I suggest you try it (after reading 
/usr/share/doc/rebase/README), without the -b option.  See also

   http://cygwin.com/ml/cygwin/2011-11/msg00215.html

for further advice about using rebase.  Two other suggestions: First, 
you could try a Cygwin snapshot (http://www.cygwin.com/snapshots/); 
there have been some improvements in Cygwin's ability to deal with fork 
failures.  Second, does uninstalling Sophos antivirus solve the problem?
