Multiprocessing returns Array, RawArray of wrong length python 3.10.4

Bug report

When initializing Array or RawArray of type int, wrong length of the arrays is returned

Reproducible example:

from multiprocessing import RawArray, RawValue, Array, Value
a = Array('d',12)
X = np.frombuffer(a.get_obj())
print(X) # [0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0.]

a = Array('i',12)
X = np.frombuffer(a.get_obj())
print(X) # [0. 0. 0. 0. 0. 0.]

a = RawArray('d',12)
X = np.frombuffer(a)
print(X) # [0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0.]

a = RawArray('i',12)
X = np.frombuffer(a)
print(X) # [0. 0. 0. 0. 0. 0.]
