I think disabling LTO as a fix is not a great idea as it may just hide
a problem.
I've fixed a similar bug in librio, where LTO exposed an already
existing undefined behavior:
https://salsa.debian.org/debian/libtrio/-/commit/23d64154ebc6e755fb0dfba90429dcebf45d4723

In my experience LTO most of the time does not _cause_ bugs, just
_exposes_ them.

I suggest keeping the current LTO-related bugs open after forwarding
them upstream since they pose no problem at the moment and a
workaround would be enough if and when LTO is enabled in Debian and
upstream did not fix the issue by then.

Cheers,
Balint
