Comment (by nickm):

 Hm.  There is a signed/unsigned bug in the handling of
 dump_microdescriptor()'s return value.  I wonder if that could account for
 this.  dump_microdescriptor() returns -1 on error, but we store its return
 value in an (unsigned) size_t, and then check whether it is less than
 zero.
