I am also cut off from testing anything - it seems the air conditioning
unit in my test site has failked for good now and the earliest I can test
anything is next week.

Yes, 5.2-rc1 was problematic in retesting, and 5.1 was OK.

I also started suspecting binutils upgrade meanwhile - I upgraded binutils
to 2.31.1-p5 in Gentoo right after booting into 5.1, but the bisection
results were finally consistent so I did not look into binutils versions
further. gcc has not changed for me recently.
