glslViewer segfaults on 3.1.1

[kruceter]

I am in progress of updating your software on void linux (with the purpose to also clean up the build template).

Everything went well except for runtime.

To reproduce this you have to abuse the "help" command on the line and get the garbled output with the core dumped in the end.

Thank you!

I wonder if this behavior is also related to #322.

@kruceter, I think it is! I just push a small diff that solves it on my side, do you mind pulling both glslViewer repo and deps/vera submodule, recompile and try recreating the issue?

@patriciogonzalezvivo, thank you for the response!

Unfortunately, I cannot compile glslViewer to reproduce the issue.

EDIT: false alarm, I could manage to compile it.

[kruceter]

The issue is still present. I do not think vera is to blame here.

gdb points at ncurses, so maybe something has to be done about it. Not sure myself.

Mmmm... weird. This fixed #322 present on MacOS, and in by Linux laptop (Ubuntu). I will keep digging
