Hello Community,
while generating C-Code from Simulink R2019b, I get the following error:
Code generation assertion 'index != -1' failed in 'b:\matlab\src\rtwcg\rtwcg_utils\rtwcg_module_reuse_buffer_insertion.cpp:354'.
Is there any idea what this message means, or, what I can do to avoid this error?
Thanks in advance

Hey Jannik,
This might be caused by some issue with internal optimization.
A simple workaround for you is to go to "Configuration parameters > Code Generation > Optimization", check "Specify custom optimizations" and turn off 'in-place bus assignment reuse', which is documented below:
This should not cause significant effect in the efficiency of your model and generated code.
Hope this helps!
