Hi,

It is a bit of reworked clone of FvwmScript-FileBrowser used in NsCDE FVWM environment. Problem manifests only in FVWM3, and FVWM2 is ok. It can be reproduced on Fedora 33 and Fedora 31, but not on other systems.

This can be reproduced by opening NsCDE Style Manager, Backdrop Style Manager, and pushing "Add ..." button. FilePicker based on FvwmScript-FileBrowser will blink for a brief moment and core dump. This is in a way similar to the It is similar to #299 (For loop on Fedora 33 and FreeBSD). It works if called manually from FvwmCommand with "Module FvwmScript FilePicker".

I'm attaching FvwmScript binary and full backtrace from Fedora 31.

Hi Thomas!

Your fix in the ta/gh-356 allowed FvwmScript to go one step further: it opens FilePicker applet. Not it dies on SendToScript in widget 1.

Hi Thomas, I've been a lot away from FVWM and NsCDE. Trying to catch what's going on this days.

You just forced be to boot VMs of recent Fedora and FreeBSD and try my own TestScript. No signal 6, no core dump.

This issue is definitely closed.
