You're welcome. To be honest, the modern C++ is complicated even for a GCC
developer like me.

For the reduction, I used C-Vise (https://github.com/marxin/cvise), so an
automated tool for reduction. For bisection I use my script which uses
pre-built binaries for all versions of the GCC (from part few years).

I'm super-fine with that word. My manager uses it quite often and I like it=
