--- Comment #4 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Ok, just verified this is already older problem e.g. with UBSAN_VPTR internal
call.
Testcase:
cp -a .../gcc/testsuite/g++.dg/ubsan/vptr-11.C .
./xg++ -B ./ -c -O2 -fsanitize=vptr vptr-11.C -o vptr-11.o -flto
./xg++ -B ./ -r -O2 -o  vptr-11.ro vptr-11.o -flto -nostdlib
vptr-11.C: In function ‘foo’:
vptr-11.C:63:8: internal compiler error: in expand_UBSAN_VPTR, at
internal-fn.c:356
   p->f ();
