Not that this is terribly relevant to the discussion, but back in the day, I did try compiling bzflag with zig cc and then with clang, and the first executable crashed, while the second worked.

Despite being told numerous compile-time options to use by different manuals and documents and people on IRC, nothing appeared to change the outcome. It might be due to some undefined behaviour in bzflag, of course, but it made zig cc a non-starter for C.

This is due to zig enabling clangs UBSAN by default in unoptimized builds. This can be disabled with `-fno-sanitize=undefined` or by enabling optimizations with `-O2` or `-O3`.

Well, as mentioned, I got a whole list of different compile-time options to try - no-this and no-that, but the executable still crashed in the end.

Please be specific with version numbers. Did you file an upstream bug already? Do you mean https://github.com/BZFlag-Dev/bzflag ? Thats c++ and must be compiled with zig c++.

Ah, well, it must have been zig c++, then, necessarily. Was I planning to file an upstream bug? I was unaware. I did contact them about it, actually, but it wasn't solved at the time.

Apropos of nothing, but found out that the zig compiler can run C++: https://twitter.com/andy_kelley/status/1391468499676008451?s...
