[Cygwin] command not found when using Windows binary and not providing command argument

Checklist

Output of fzf --version

Problem / Steps to reproduce

I have installed the Windows binary into C:\bin\fzf.exe, which is in my Cygwin path.
I have included the line eval "$(fzf --bash)" into my .bashrc.

I open Cygwin shell, no errors.

I hit [CTRL]+R, I get an error that make no sense:

C:\cygwin64\tmp\fzf-temp-3974864139: line 1: C:\bin\fzf.exe: command not found

If I run from bash fzf I get the same error.
If I run from bash fzf --help (or any other option) Fzf seem to work with no error.

It only breaks when given no argument!

PS. There is no recent version for fzf package. Do not use Cygwin package!

export MSYS=enable_pcon works for me on Cygwin.
