Replying to rouault:

Using the C++ API isn't recommanded from the exterior of GDAL if you don't use the same compiler & compiler options in both your program and GDAL.

The error in your code is to call oPolygon1->addRingDirectly(&oLR1); that will take ownership of the linear ring and try to delete it. You should rather use addRing() that will make a copy (or dynamically allocate the ring with new, but then you can run into cross-heap issues)

Sorry, I used addRing(), then the crash occurred too.
