[Linux] Freeze on map load

rkfg

This started to happen on the "Downloading mods" stage recently. The game just freezes randomly. Here's the traceback:

Seems to be a deadlock. I'm not 100% sure but it started really not so long ago, maybe an update or two back.

Hi, the usage of tbb will be removed with upcoming build to avoid issues like this one. However there may be some new issues at Linux due to the switch to 64bit and the related code and libs changes.

To run the beta you will need gcc-5 and g++-5.

Good, the best way to fix the faulty code is indeed to remove it (no irony)! I have several GCC and G++ installed, from 5 to 7, but it's a kinda weird requirement for an end user. Maybe you mean libstdc++ that's often the source of issues?

Yeah I meant libstdc++-5.

Frozen again on mapload, the trace is a bit different this time:
