Thread safety

[chrispap95]

While troubleshooting configuring and building on MacOS, I realized that we haven't enabled the thread safety option that exists since 3.4.0. Do we want to recompile with that on? I am wondering whether this would solve the issue in #131 without that ugly patch.

That we should give a try - given the annoyingness of getting macos to go and that it should not stop us from releasing 3.4.0.0. I'd check quick and if it simplifies the build in linux good.

After testing this on my fork, unfortunately, the seg fault is resolved by neither --enable-limited-thread-safety nor --enable-thread-safety. Nevertheless, both options seem to pass the tests as expected when the patch is applied. However, I am not sure how useful they are in our use case. (I have a feeling they are not)

I don't think this is important for now so closing. Feel free to reopen if necessary.
