Crash in nested dgsh execution #23

Closed dspinellis closed 7 years ago

dspinellis commented 7 years ago 
$ dgsh -c 'dgsh -c "{{ echo hi & echo there & }}" | paste'
/home/dds/libexec/dgsh/bash: line 1: 16110 Done                    dgsh -c "{{ echo hi & echo there & }}"
     16111 Segmentation fault      (core dumped) | paste

The second command (e.g. paste or cat) crashes.

That's not very friendly whatever the cause. That said, the problem is that the inner dgsh is expected to negotiate, but it doesn't.

dgsh -c 'dgsh --dgsh-negotiate -c "{{ echo hi & echo there & }}" | paste' 2>err there hi

Excellent! I didn't know (or had forgotten about) that option. I added a note in the documentation.

The correct form is:

dgsh -c 'dgsh -c "{{ echo hi & echo there & }}" | paste'
