Can you try trunk or 17 instead? 16.0.6 was the last 16.x release, so even if it’s a bug on our side and we will fix it, it won’t be available on 16 branch.

I can’t see it from the screenshot, there’s not enough information, but is this a segfault in your host compiler? In GCC-10? Might be a GCC problem then. Can you try with a different compiler.

I’d suggest you to update the compiler to the newest version possible and then, if the internal compiler error is still there, report it to the GNU community.
