[issue32782] ctypes: memoryview gives incorrect PEP3118 itemsize for array of length zero

Terry J. Reedy added the comment: This issue is about the itemsize attribute of instances of the built-in memoryview class. Ctypes in only involved in providing format information. Hence the nosy additions. On Win10 with 3.8, ctypes has no uint attributes. Using 'c_int32' instead, I see

[issue32782] ctypes: memoryview gives incorrect PEP3118 itemsize for array of length zero

New submission from Eric Wieser : Take the following simple structure: class Foo(ctypes.Structure): _fields_ = [('f', ctypes.uint32_t)] And construct some arrays with it: def get_array_view(N): return memoryview((Foo * N)()) In most cases,
