Please make sure that your qemu isn't too old.

I noticed this last night, but I haven't looked into it yet. I don't know if it's because of the qemu version, but seems it's happening in our CI too: https://github.com/rui314/mold/runs/8182926219?check_suite_focus=true#step:6:296

Interesting. It seems like a GCC's bug, so I reported to GCC developrs.

Yet another GCC issue: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=106835

I implemented a workaround in bb0e601.
