I have made some more experiments with a fresh installation of 
http://isabelle.in.tum.de/cygwin_2016 on Windows 8.1 and 
Isabelle/b737f8f37454.

It all works as expected. I cannot see any problems with bash_process.


The speculative problem about "rebasing" executable does not exist: DLLs 
can be rebased, but not EXEs. See also 
http://isabelle.in.tum.de/repos/isabelle/rev/9d7ba380223c where this was 
once done for the DLLs of Poly/ML, but later discontinued because it 
became native on Windows.
