Subject: [Bug sanitizer/59415] ICE segfault in verify_bb_vtables for g++ -S -fvtable-verify=std -fsanitize=null

Message-ID: <bug-59415-4-8Rm4WSNWgd@http.gcc.gnu.org/bugzilla/> (raw)

--- Comment #1 from Tobias Burnus <burnus at gcc dot gnu.org> ---
It fails in

575     verify_bb_vtables (basic_block bb)
...
589           if (gimple_code (stmt) == GIMPLE_CALL)
590             {
591               tree fncall = gimple_call_fn (stmt);
592               if (TREE_CODE (fncall) == OBJ_TYPE_REF)

There, one has:

(gdb) p debug_bb(bb)
<bb 2>:
UBSAN_NULL (this_1(D), 3);
_2 = this_1(D)->_M_dataplus._M_p;
