The function isar_render_poses() differs between BASOP and float in sanity check for memory allocation. The function was originally introduced under `FIX_1119_SPLIT_RENDERING_VOIP`. Moreover, the the length of the flushbuffer is not correct in BASOP - it is twice as long wrt. the buffer in the float framework. The functions should be aligned. <!--Commandline or script--> ```bash ``` <!--- Below are labels that will be added but are not shown in description. This is a template to help fill them.
