I am having this same issue with OpenBSD 7.1. I tried to build [libunwind](https://github.com/libunwind/libunwind) from source but it requires `getcontext` and OpenBSD does not provide `getcontext` from POSIX ([see here](https://www.gnu.org/software/gnulib/manual/html_node/getcontext.html))....

> Can you see what OpenBSD's C++ runtime (libcxxrt, libsupc++, or libc++abi) links to? I'd be happy to, but I must admit, I'm pretty novice to C on unix/linux world...
