[Nix-dev] Trouble packaging llvmlite, Python bindings for LLVM

[Thomas Hunger]

Hi Freddy,

I ran into the numba segfault as well [1]. I tried to debug the issue with
a numba core dev when in the same room but we didn't make any progress in
an hour. Potentially a double-free bug. Probably worth filing an issue
which I forgot to do.

In [1]: import numba
