Jan Vesely:

updating scipy to 1.4 results in:

```

the attached log is for:

```
$ pypy3 --version
Python 3.6.9 (5da45ced70e515f94686be0df47c59abd1348ebc, Nov 02 2019, 18:56:40)
[PyPy 7.2.0 with GCC 8.3.0]
```

but the same problem appears in:

```shell
$ python --version
Python 3.7.4 (47c4c0ed3274, Dec 20 2019, 17:37:49)
[PyPy 7.3.0-alpha0 with GCC 9.2.1 20190827 (Red Hat 9.2.1-1)]
```

and:

```
$ python --version
Python 3.6.9 (574325fb0c26, Dec 20 2019, 17:38:07)
[PyPy 7.3.1-alpha0 with GCC 9.2.1 20190827 (Red Hat 9.2.1-1)]
```

scipy 1.3.x works OK.
