Can you check whether your GC was built with --enable-parallel-mark? I=E2=80=99m confident that the SMOB mark procedure is never called with null scm_i_current_thread with 7.2 compiled with the default options (the GnuTLS bindings rely on this, and I had not seen any such report until someone tried with GC 7.3pre, which uses the parallel marker by default.)
