I now managed to build gtk with a debug output and meson configure flag
"-Dc_args=-O0".

For drawing-widget.scm on x86_64, klass->snapshot looks high like a code
segment address but has a bogus disassembly.  Was it clobbered?  Should
klass->snapshot be a procedure calling drawing-widget.scm’s snapshot
procedure?  Probably I’m misinterpreting.

Thread 1 "guile" received signal SIGSEGV, Segmentation fault.
