As per summary, app-office/libreoffice-7.1.3.2 fails to compile with gcc-11.1.0 on ~amd64 (-march=core2), (see below for USE flags and {C,LD}FLAGS). The system (~2400 packages) has been almost entirely rebuilt with gcc-11.1.0. Excluded are known-failing packages as per the gcc-11 tracker bug, those explicitly invoking clang, or for packages for which a particular gcc version is irrelevant (such as other versions of gcc itself). Libreoffice is the only problem build... The error thrown relates to the .../bridges/source/cpp_uno/gcc3_linux_x86-64/callvirtualmethod.cxx file, line 109: '"movq (%%rax), %%rdi\n\t"' which causes the compile to fail with the diagnostic output: 'Assembler messages:' 'Error: junk `80' after expression': [CXX] bridges/source/cpp_uno/shared/component.cxx /usr/portage/tmpdir/portage/app-office/libreoffice-7.1.3.2/work/libreoffice-7.1.3.2/bridges/source/cpp_uno/gcc3_linux_x86-64/callvirtualmethod.cxx: Assembler messages: /usr/portage/tmpdir/portage/app-office/libreoffice-7.1.3.2/work/libreoffice-7.1.3.2/bridges/source/cpp_uno/gcc3_linux_x86-64/callvirtualmethod.cxx:109: Error: junk `80' after expression I assume this is exposing a bug in the assembler routines in gcc-11.1.0, rather than being a libreoffice bug per se, as gcc-10.3.0 was not tripped up by this file (compile not yet completed with latter compiler version - seven-hour job on an Intel Core 2 - but well past the problem file).

Is the libreoffice build known to ignore a modified portage environment?) Thanks. Reproducible: Always
Thank you for the report. We need to have all information at hand before ticket assignment. That is why I ask you to * attach the logs and * paste the emerge info as described on https://wiki.gentoo.org/wiki/Attach_the_logs_to_the_bug_ticket Please reopen this ticket (Status:UNCONFIRMED) afterwards.
