Ok, I've found out the issue. It's related to MinGW issue with
thread_local https://github.com/boostorg/config/blob/21830e11ff5ee114c0c6d9fbf9f3b48b7b067e18/include/boost/config/compiler/gcc.hpp#L307-L310

Fixed it here: https://github.com/boostorg/stacktrace/commit/cd420b37ae7e84196cdb8202e489d5d276c55f0b
Do not forget to add --reconfigure while running you b2 with the patch
from above.
