That's... incredibly strange. I really don't know why that would happen.

That's a miracle which holy C++ gave us. Some heretics call it UB..
I see two possible reasons:

  1. My build options (in attachment)
  2. My system configuration (especially my enormous 48GB of memory and 10/20 cored CPU)

This happens when ENABLE_LTO + gcc.
gcc w/o LTO and clang with and w/o LTO are working fine.

Little update: clang LTO got segfault on "shutting down" stage. When running under gdb it can't start, just segfault like gcc. So, it looks like a race condition or something like that.
