  new_block(0) in turn calls malloc_block.  malloc_block can return NULL if
  no space is available.  Since address is dereferenced, this produces a
  sigsegv, right?

Yep.  This is an error check I somehow forgot to insert ages ago.
(NB the failure has come back to haunt me since).  Please feel free
to submit a patch.
