Comment (by kalenik):

 My case is calculation of buffers for heavy geometries in parallel and the
 problem is that at some point I am running out of memory and process
 crashes badly. I understand that with current implementation buffer
 calculation for heavy geometries is memory consuming process but I would
 prefer GEOS to throw an exception instead of crashing.

 Here is the C snippet and geometry file I used to reproduce the problem.
 Likely you would have to limit process memory to reproduce the OOM.
