Are you sure you have object files compiled with the same compiler as you link
with?

I just compiled it again. Yes, I have the same compiler.
It looks like a mismatch in LTO readers and writers to me.
Would the .i file that is upstream of the .o file help ?

Note that we don't bump LTO bytecode version during the development of a GCC
release (stage1-4). Once we do a release, we keep eye on it.

Yes, that could possibly reproduce the issue. Is the ICE happening in the
WPA process? (add -v so you'd see that)

It now fails to reproduce. Odd. Maybe the OS upgrade over the weekend
(Fedora 35 to 36 Beta) has something to do with it.
I am happy to close this one down as not reproducible.
I am not familiar with the WPA process, but I used -v and didn't see it
(gcc -v ... 2>&1 | grep -i wpa).

No problem - just open a new bug if the issue pops up again.
