--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
We output from fn->local_decls 'i' which has a DECL_VALUE_EXPR of
((struct A *) (struct B *) this + (sizetype) *(long int *) ((UBSAN_VPTR
((struct B *) this, (long unsigned int) ((struct B *) this)->_vptr.B,
18446725456357140888, &_ZTI1B, 9B);, (struct B *) this;)->_vptr.B +
18446744073709551592))->i
I think we need to prune sanitizer instrumentation from DECL_VALUE_EXPRs
somehow.
-> sanitizer issue.
