test_bisplev_integer_overflow: Segmentation fault (core dumped)

[Lechnio]

After scipy 1.4.1 instalation I have run the tests with

$ python3
>>> import scipy
>>> scipy.test()

and the 'test_bisplev_integer_overflow' test exited with Segmentation fault (core dumped). I added few prints that can help me to trace this issue (I do not have dev/debug tools on my target device), and what I figured out, the seg fault occurs on call:
scipy/interpolate/src/_fitpackmodule.c:198

197: else {
198:         BISPEV(tx, &nx, ty, &ny, c, &kx, &ky, x, &mx, y, &my, z, wrk, &lwrk,
199:                iwrk, &kwrk, &ier);
200: }

BISPEV is not NULL here and has an address assigned, but I could not debug it deeper, since seg fault occurs just after this call.
I have been testing this for a while and the bisplev function works in other cases (e.g. example codes from https://docs.scipy.org/doc/scipy-1.4.1/reference/tutorial/interpolate.html), I only noticed problem with input data from the mentioned test.

Error message:

When I run test_bisplev_integer_overflow line by line in python console:

On my intel host:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/lechnio/.local/lib/python3.6/site-packages/scipy/interpolate/_fitpack_impl.py", line 1054, in bisplev
    z, ier = _fitpack._bispev(tx, ty, c, kx, ky, x, y, dx, dy)
RuntimeError: Cannot produce output of size 2621440x2621440 (size too large)

I expect the same output for my target device.

On my target device:

>>> interpolate.bisplev(xp, yp, tck)
Segmentation fault (core dumped)
