Basic info

• Fixed point:
  • Renderer (fixed): 6ab3ac9e

Bug description and Ways to reproduce

While analysing the remaining differences of #1724 (closed) more closely, crashing behaviour is observed for META inputs to the renderer with MASA and MC components.

The crashes occur in ivas_mcmasa_param_est_ana_fx, but in different locations.
