Are you using bash-completion?  If so, it's likely a bug in
bash-completion for passing an underquoted file name through the shell
such that it results in a failed globbing attempt on a literal \.

I haven't yet managed to reproduce this in my setup (perhaps I need to
double-check that my $CYGWIN hasn't already suppressed the warning?).
Maybe showing:

$ set -vx
$ pushd ~/myuserdrv/My\ Down[TAB]

might give me some insight where to look at plugging the leak?
