Help: cygheap base mismatch detected

[Jim Reisert AD1C]

I installed the latest Windows 10 update this morning and rebooted.
Now Cygwin won't work at all.  Using the latest test release of
Cygwin:

CYGWIN_NT-10.0-WOW JJR 2.3.0(0.291/5/3) 2015-10-22 17:54 i686 Cygwin

Any ideas?

F:\>dash
$  rebase-trigger fullrebase
      0 [main] dash (4564) C:\Cygwin\bin\dash.exe: *** fatal error -
cygheap base mismatch detected - 0xABB400/0xD1B400.
This problem is probably due to using incompatible versions of the cygwin DLL.
Search for cygwin1.dll using the Windows Start->Find/Search facility
and delete all but the most recent version.  The most recent version *should*
reside in x:\cygwin\bin, where 'x' is the drive on which you have
installed the cygwin distribution.  Rebooting is also suggested if you
are unable to find another cygwin DLL.
