Bug#936076: python3-numba: numba segfaults when run with python 3.7.4 at numba/_dynfunc.c:52

[Diane Trout]

Package: python3-numba
Version: 0.42.0-1
Severity: grave
Tags: upstream
Justification: renders package unusable

Dear Maintainer,

Attempting to run any numba code immediately segfaults when running with python
3.7.4.

I found this upstream bug report.
https://github.com/numba/numba/pull/4328

"CPython 3.7.3->3.7.4 changed the size of PyGC_Head, the macro
_PyObject_GC_UNTRACK relied on calling sizeof() on that struct, as it is a
macro it got baked in at compile time and then segfaults happen across the
point version change as the struct size changed."

The simplist solution is to rebuild with python 3.7.4... though then it'll
crash with earlier versions.

Diane
