I would guess that something like

foo=`bar`

is what is causing the problem because this uses a pipe for
communication.  In a shell that is run from setup.exe, it is possible
that stdin is not opened at all and stdout is the pipe in question.
Maybe this is somehow confusing the SHF* function.

So, the question is does something like this also hang?

#!/bin/bash
exec 0<&- 1>&- 
cygpath -S | cat

when invoked from the command line?  Or possibly via "Run"?
