Is the API still working?

[gdonval]

I am trying to generate limited bindings with Cython (I know there is a pybind11 binding already).

I can get the device to start, instantiate a camera and a simple mesh geometry but when trying to embed the geometry in a geometry model (ospNewGeometricModel(mesh)), I get a

'python test.py' terminated by signal SIGSEGV (Address boundary error)

I get the same error whatever I do with OSPData. The guy doing the pybind11 bindings is not using the API so I was wondering if it was simply broken.

I don't know how to make things simpler than this (minimum wrapping with cython). It fails when committing the model.
