Hmm, just tried that, now running "dumper" does nothing:
Baube@DESKTOP-42816MD ~
$ dumper
Baube@DESKTOP-42816MD ~
$ echo $?
127
One thing that's weird is that in my installation, binaries are in C:\cygwin64\bin,
whereas in the snapshot, they are in usr/bin. Did the filesystem layout change
recently?
So I am not sure how to proceed to try the snapshot.

I successfully repaired my broken dumper by re-installing the cygwin* packages.
