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.
