Comment (by Algunenano):

 By following the `/* COMPUTE_BBOX TAINTING */` comment I see this affects
 `LWGEOM_SetEffectiveArea`, `LWGEOM_ChaikinSmoothing` and
 `LWGEOM_snaptogrid`, `LWGEOM_snaptogrid_pointoff`.

 The fix is simple, but I'll try to come up with test to along with it for
 each function.
