Have you tried set disable-randomization off prior to running (which causes some heisenbugs to show up again) and/or compiling with -fbounds-checking and breaking on __bounds_breakpoint? I don't have a *nix system handy but I can spin up a VM if I can help, but I'm not even remotely familiar with the inkscape codebase....
