I patched the drawing-widget example so users may pass a -d or --debug
option, which triggers the setting of the %debug parameter.
This will track (some of the) g-golf (engine) calls 'only', so in this
particular situation that it segfault (in guix) upon a gtk snapshot
engine call, i probably will still very much need you to upload the
full gdb backtrace.
But it will at least give you some useful info on what's going on
'internally' - and who knows, might also give me some idea to further
investigate the problem ... tracking those calls is also a nice way to
learn about some g-golf internals ....
I pushed the patch to the devel branch, commit
8fbc8c27774986b4b5ad09a6545698b3e3ee1812, so, could either grab the
latest devel branch version, or simply grab the latest version of the example
https://git.savannah.gnu.org/cgit/g-golf.git/tree/examples/gtk-4/drawing-widget.scm?h=devel
then try (as shown below) and post the result here ...
Thanks,
David
