Segfault on creating a Ctx

See original GitHub issue

Installation using conda with Python 3.6.2 on Ubuntu 16.04.

tiledb                    1.2.2                h650255c_2    conda-forge
tiledb-py                 0.1.1                    py36_0    conda-forge

@manolinux I think your issue is different than the one above. The illegal instruction issue hints that the conda toolchain compiled with SSE or AVX vector instructions that your platform does not support.

Hi @nvictus, this looks to be an internal TileDB bug from the last version. We are working on getting ready for the next release (1.3.0) next week and I think this should be addressed.

I’ll leave this issue open until I can reproduce / confirm.
