I didn't check that myself, but the Debian LibreOffice maintainer claims th= at he sees the same symptoms when building with some GCC 11 (against some GCC = 12 libstdc++, though). (It appears that this issue only happened to start to = hit builds of LibreOffice after some recent code changes in LibreOffice, so we don't have any historic data on which versions of GCC would not have had th= is issue.)=
