The
IsCTypesArrayOrPointer
gives false positives in Python 3.13, resulting the void pointer converter to take the wrong code path and crash. See:wlav/cppyy#272
This code path is used for implicit conversion from other
ctypes
pointer types tovoid*
, which is not strictly required. One can always do an explicit cast:ctypes.cast(my_ptr, ctypes.c_void_p )
.Given that this a niche feature that broke Python 3.13 support for functions taking
void*
, which is quite common, it can be argued that it's better to remove this implicit conversion.This commit fixes the following tests under Python 3.13:
