I have reproduced the problem with a test case. The problem is in cython. It generates code with this type of problem in some cases (inlined methods of derived classes). I have reported the problem upstream https://github.com/cython/cython/issues/6033 I don't know how to continue from here. Is it possible to build C code with the old behaviour?
