Are you referring to the error about _ZTI11QSharedData@Qt_5 in my last comment,
or the original issue? The system libQt5Gui was indeed built with GCC 11.1 but
the error came from building nextcloud-client with GCC 11.2 and binutils 2.38.
It also went away after applying your earlier diff.

If you meant the original issue:

I'm using GCC 11.2. I grabbed heif_info-heif_info.o from the failed libheif
build so generating its proproccessed source counterpart isn't very
straightforward for me.

However, I can provide a repro.sh that builds libheif from source and
reproduces the undefined references on GCC 11.2 + binutils 2.38; would that
help?
