Only with --enable-link-serialization, or without that too?
It's the default, i.e. without --enable-link-serialization.
Will have a look.
Thanks.
I see the same, I don't use --enable-link-serialization.
Just run:

Reposting with self-contained description per Joseph's request:
When performing LTO bootstraps, especially when using tmpfs for /tmp,
