Segfault running test_linalg and linalg.eig

[reazulhoque]

The following reproducer segfaults with dpnp 0.4.0

import numpy as np
import dpnp

size = 3
type = np.int32
a = np.ones((size, size), dtype=type)
symm_orig = np.tril(a) + np.tril(a, -1).T + np.diag(np.full((size,), size * size, dtype=type))
symm = symm_orig


dpnp_symm = dpnp.array(symm)
print(dpnp.linalg.eig(dpnp_symm))

Here is the output:

DPNP: Module NumPy found. Please load DPNP module before NumPy.

  warnings.warn("\nDPNP: Module NumPy found. Please load DPNP module before NumPy.\n")

Also running the following command ends up in a segfault too:

pytest dpnp/tests/test_linalg.py

Here is the output:
