C++ test case "test48.ii", run with g++ -fvtable-verify=std -fsanitize=null

Follow up to PR59415; the fix is probably similar to that PR, cf.
gcc.gnu.org/ml/gcc-patches/2013-12/msg00839.html

The attached test case fails with "g++ -S -fvtable-verify=std -fsanitize=null"
as follows:

test48.ii: In function 'basic_ostream<_CharT, _Traits>&
endl(basic_ostream<_CharT, _Traits>&) [with _CharT = char; _Traits =
char_traits<char>]':
test48.ii:21:3: internal compiler error: Segmentation fault
   endl(basic_ostream<_CharT, _Traits>& __os)     {
