Describe the bug gtkf-sketcher crashes both in gtk3 and gtk4 branches. Crashes happen on any .glade file opening attempt. gtk4 crash on example.glade export attempt <- the only case of program opening gtk3 crash on example.glade opening attempt

Thanks @lllaxmatist for reporting,

I can confirm this MSYS/Windows 10 bug. I have obtained the same segfault message, although curiously at first launch only I also had a lot of:

(process:11752): GLib-GIO-CRITICAL **: 20:54:43.315: GFileInfo created without standard::type

(process:11752): GLib-GIO-CRITICAL **: 20:54:43.316: file ../glib-2.80.0/gio/gfileinfo.c: line 1610
(g_file_info_get_file_type): should not be reached

(Quite similar to https://gitlab.gnome.org/GNOME/gimp/-/issues/9994)

Unhappily, most of the time bugs encountered in MSYS2 or macOS are on the GTK side and we can not do much, just report it when we have enough information. When possible, I will try also on macOS or FreeBSD.

Note also that gtkf-sketcher was never totally ported to GTK 4 due to important API changes: https://github.com/vmagnin/gtk-fortran/issues/207 I would say that the probability that I will never succeed porting it (by lack of knowledge and lack of time) is well >50%.

Interestingly, gtk4 branch also crashes on FreeBSD when clicking on "Write Files":

But it may be another problem (" EXECUTE_COMMAND_LINE: Invalid command line").
