Given that you are using static linking with lto make sure you have rebuilt all static libraries with new gcc: https://gcc.gnu.org/PR62083

I've enabled lto selective for some packages, but not for qemu. Does this error come from a package build with lto and is linked in by qemu? I'm suspecting glib.

Oh, that's an interesting failure mode. Yeah, that might be it. Ideally such static libraries should be built with -ffat-lto-objects, so these .a files could be used in non-lto contexts.

Nailed it! Re-emerging dev-libs/glib solved it. I'm building dev-libs/glib with the this flags:

COMMON_FLAGS="-O2 -ggdb -flto=8 -fuse-linker-plugin -march=znver1 -mtune=znver1 --param l1-cache-size=32 --param l1-cache-line-size=64 --param l2-cache-size=512 -ftree-vectorize -fvect-cost-model -pipe"

Glad you've nailed it! If the mere rebuid was enough then it probably was a mismatch of lto formats (or contents) across gcc versions.
