Jakub Jelinek <jakub at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jakub at gcc dot gnu.org --- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Seems if I compile the testcases with clang++ -S -fsanitize=vptr instead of g++ -S -fsanitize=vptr and then link against gcc 5.0 libubsan, it emits the same runtime error. If I link against llvm 3.5.0 libubsan the g++ -fsanitize=vptr -S compiled test, it works. So I think this must be a library issue.
