This fails on i686-linux: FAIL: g++.dg/cpp1y/udlit-char-template-vs-std-literal-operator.C -std=c++14 (test for excess errors) Excess errors: /home/jakub/src/gcc/gcc/testsuite/g++.dg/cpp1y/udlit-char-template-vs-std-literal-operator.C:10:51: error: 'int operator""_script(const char*, long unsigned int)' has invalid argument list Perhaps you meant to #include <cstddef> too and use size_t instead of unsigned long? Or just __SIZE_TYPE__ instead of unsigned long? Jakub
