[geos-devel] Checking GEOS master (state 8 October)

[Roger Bivand]

I've been checking the possible fallout from Overlay_NG (assuming that 
building from master on 8 October uses the new code) in some R packages, 
in particular sf and rgeos. I see messages such as:

CBR: result (after common-bits addition) is INVALID: Self-intersection at 
or near point 368576.69999999995 864696 (368576.69999999995343 864696)

followed by the text representation of the object dumped to console. The 
message and the dumped object are not passed through error or warning 
handlers passed in through initGEOS_r(), and so are hard to trap and 
handle. Is this a temporary feature which will be normalised for 3.9.0?

So far I don't think that there are obvious failures in R packages related 
to the new code (again assuming that a straight build of master of 8 
November exercises Overlay_NG), but the unexpected output was surprising.

Best wishes,

Roger
