I tried this on FreeBSD, since I don't have an OpenBSD machine, with the llvm80
port, which also has clang version 8.0.1 (tags/RELEASE_801/final), so I had to
remove the non-standard -ret-protector command line option.

It compiled just fine, and took ~813 MiB of resident memory:

Does your error go away if you remove -ret-protector? If so, the problem lies
in that OpenBSD specific addition. Otherwise, your machine may just be low on
memory?

Thanks for your investigation.
I'm running this OpenBSD on vm and it has 2GB RAM.
I had removed "-ret-protector" and tried again, but still fail with the same
error.
I'll try to see if there's another reason for this.

Kinichiro,

Please try out a -current snapshot. -current was just upgraded from 8 to 10. Let us know if there was any improvement.
