Comment (by Algunenano):

 It appears than a tolerance of 0.0 to remove repeated points in
 `lwcompound_linearize` is too small in 32b systems.

 Using DBL_EPSILON also doesn't work (kind of expected), but FLT_EPSILON
 works. I'm reviewing `lwarc_linearize` to see if we can do anything there
 to improve the precision of 32 bit systems; if not I'll just increase the
 tolerance to FLT_EPSILON.
