Yes, I’ve retested with the combination of all binutils:
2.32, 2.34, 2.35.2 and 2.36,1 against:
gcc9,10 and they worked correctly on gcc10 with any binutils. I haven’t dig the reason inside gcc but that is what I’ve seen.

Honestly this showed up only with gcc8 as I remember and it still does it with Bootlin toolchain
on autobuilder(gcc9+binutils 2.33.1).
