--- Comment #1 from Markus Trippelsdorf <trippels at gcc dot gnu.org> ---
Please try to narrow down the issue and attach prepossessed testcases
(of fmgridif.cxx and ColumnControl.cxx for a start).
Also find out where the `non-virtual thunk to
WindowListenerMultiplexer::acquire()' comes from in a successful build.
(add -Wl,--no-demangle to the link command, and search object files 
for the unmangled symbol.)

Nobody will git clone LibreOffice just to reproduce the problem.
