Description

During clone of a repo desktop barfs, complaining

      1 [main] sh (21312) C:\Users\bdorrans\AppData\Local\GitHubDesktop\app-1.0.4\resources\app\git\usr\bin\sh.exe: *** fatal error - cygheap base mismatch detected - 0x2FA7408/0x2D97408.
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.

There is no cygwin1.dll anywhere on any disk that I can find.

Git standalone, version 2.14.2.windows.3, 32bit is installed. It is higher in the path, however uninstalling it and rebooting made no difference.
