https://gcc.gnu.org/bugzilla/show_bug.cgi?id=63813 --- Comment #7 from Jakub Jelinek jakub at gcc dot gnu.org --- Author: jakub Date: Tue Nov 18 22:15:42 2014 New Revision: 217741 URL: https://gcc.gnu.org/viewcvs?rev=217741root=gccview=rev Log: PR sanitizer/63813 * c-ubsan.c (ubsan_maybe_instrument_reference_or_call): Change type argument to ptype, set type to TREE_TYPE (ptype). Don't call get_pointer_alignment for non-pointers. Use ptype, or if it is reference type, corresponding pointer type, as type of kind argument. (ubsan_maybe_instrument_reference, ubsan_maybe_instrument_member_call): Adjust callers. * g++.dg/ubsan/pr63813.C: New test. Added: trunk/gcc/testsuite/g++.dg/ubsan/pr63813.C Modified: trunk/gcc/c-family/ChangeLog trunk/gcc/c-family/c-ubsan.c trunk/gcc/testsuite/ChangeLog
