External renderer/split-prerenderer crashes when rendering OMASA

When used as split-pre renderer for OMASA, the external renderer crashes due to a misconfiguration:

Assertion failed: (( buffer->config.is_cldfb == 1 ) && "for time domain input call copyBufferTo2dArray()"), function accumulateCLDFBArrayToBuffer, file lib_rend.c, line 379.

Can be reproduced by attempting to render any OMASA input to BINAURAL_SPLIT_CODED:
