Segmentation fault importing module

[ZXGuesser]

On Debian with Python 3.11.2, I'm getting a segfault in __strlen-sse2(), called from PyUnicode_FromString(), which I've narrowed down to the calculation of the n_in_sequence for the PyStructSequence_Descs in zvbi_event_types.c

for example sizeof(ZvbiEvent_EventNetworkMembers) / sizeof(ZvbiEvent_EventNetworkMembers[0])

If I hard code all these values instead the module loads and the appears to work as expected.
