This is weird because that variable is being used. However, it's being used inside assert() statements. Maybe assert() has been overloaded to a no-op (somehow?). Maybe something like this:

#define assert(ignore) ((void)0)

[martin-belanger]

Actually, we should not build the test code when building PyPI. Let me fix the meson files.

Seems to be fixed with #3050

Thanks!
