Insert printfs in scm_igc () (gc.c) and scm_i_sweep_all_segments()
(gc-segment.c), the argument they take is the type of object being
allocated. Also, you could insert a

  scm_display(scm_gc_stats(), scm_current_error_port ())

at the end of scm_igc, halfway in scm_gc_for_newcell().

Also there's some printfs in gc-malloc.c that you could switch on.
