[geos-devel] Buffer(box3d()) not returning same SRID

[Tyler Mitchell]

What's the SRID handling logic that goes on when I embed functions like:
buffer( box3d ( wkb_geometry ) )
If I'm comparing this with other geometries that initially had the same 
SRID, I find I have to add:
setsrid(buffer( box3d ( wkb_geometry ) ),nnnnnn)
to make it work.  Yet if I only use Buffer or box3d I don't get this 
problem. 

I know my example is a bit weird but bear with me...
