--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Some sanitizers imply -fno-delete-null-pointer-checks and this testcase fails with fno-delete-null-pointer-checks too - the &heap_magic_var_decl != NULL comparison in that case which is done on delete is not folded into true. Wonder if at least for the magic heap vars we shouldn't fold comparisons against NULL, because those will never live in any memory and thus we can pretend their address will never be 0.
