Bug#864365: A simple program ends up with SIGSEGV [amd64]

[Lumin]

Control: tag -1 +patch

The fix is attached. It fails on my side simply
because the python3-llvmlite package is too
old.

The default version in sid (0.16.0) does not
work with numba.

Listing... Done
python3-llvmlite/experimental,now 0.18.0-1 amd64 [installed]
python3-llvmlite/unstable 0.16.0-1 amd64

The numba package installed with pip3 seems working.
It is able to run numba.runtests.main()

However the Debian package will segfault immediately
if you do so.

Yup. That's why it's still in experimental ... :-)

Package: python3-numba
Version: 0.33.0-1
Severity: severe

Hi,

It fails to run even the simplest code:

```
#!/usr/bin/python3
from numba import jit
from numpy import arange
import time

@jit
def sum2d(arr):
M, N = arr.shape
result = 0.0
for i in range(M):
for j in range(N):
result += arr[i,j]
return result

a = arange(65536).reshape(256,256)
t1 = time.time()
print(sum2d(a))
t2 = time.time()
```

terminated by signal SIGSEGV (Address boundary error)
