Re: GNU G-Golf 0.8.0-rc-3 available for testing

Hi David, thank you for your continuing responses.  I will try to get a
backtrace with GTK debug symbols by patching Guix to add a debug output
to GTK, in the hope that I patch the right GTK.

However, my believe is that the error is in G-Golf
closures/callbacks/vfuncs (even though the hl-api tests do pass when run
by Guix build or manually), specifically when I run valgrind on guile
where I load and run drawing-widget.scm, it only shows errors from Boehm
GC (at least mostly false-positive) and from creating threads, but no
errors from GTK.  In particular there are errors in scm_c_make_vector,
probably false positive, but I will look at bytevectors this weekend now
(occurrences of bv in g-golf code).

I cannot tell you my host distro because there is none (there could be a
foreign distro, but I have none).  It is Guix System, that is Guix all
the way down.

To build G-Golf manually, I can and had patched the its g-golf/init.scm
to use /gnu/store/xxxxxxx/lib/libgirepository-1.0.so file names like the
guile-g-golf package at
<https://git.savannah.gnu.org/cgit/guix.git/tree/gnu/packages/guile-xyz.scm>
does, but it will not be useful.

Setting the GTK_A11Y env var does not make a difference (except the
warning is gone) and on my x86_64 GNOME setup there never is a warning
(although GTK_A11Y is unset, but d-bus is there).

Regards,
Florian
