This is a known compiler bug. Apple Clang 13 crashes when compiling some vg sources on an M1 Mac running macOS Monterey. You may try reporting the issue to Apple, and they may eventually fix it. Until then, the only known solution is using another computer. Downgrading to macOS Big Sur may also help if your computer supports it.
Do we need to do something to work around this bug, such as developing Mac build instructions that give a procedure for installing and building with a fixed compiler?
I'm not sure there is a fixed compiler.
I get similar crashes when compiling GBWTGraph tests on my M1 laptop, so the crash is probably caused by libhandlegraph code.
After updating to macOS 12.3 and command line tools 13.3, everything seems to be working again.
