Comment (by Algunenano):

 After testing it, the only affected functions are LWGEOM_snaptogrid and
 LWGEOM_snaptogrid_pointoff, since LWGEOM_SetEffectiveArea and
 LWGEOM_ChaikinSmoothing don't reuse the input and the output doesn't have
 a bbox (so it's calculated with lwgeom_add_bbox).

 I've added tests for all 4 functions and the fix for the 2 affected by the
 issue in https://github.com/postgis/postgis/pull/473
