           Version: 8.3.0
            Status: UNCONFIRMED
          Severity: normal

  Target Milestone: ---

Buildroot hangs on building package "bullet" when compiling with g++ and
optimization >= -O2, it's noted instead that the problem doesn't show anymore
using -O1 as a work-around. Nothing changes trying to build with/without debug
symbols.

Here is build hang log:
