ICF will newly merge these functions: grep hit: Wstringop-truncation-4.c.070i.icf Semantic equality hit:void test_arrays(Arrays*, const char*)->void test_const_arrays(ConstArrays*, const char*) Semantic equality hit:void test_arrays(Arrays*, const char*)->void test_volatile_arrays(VolatileArrays*, const char*) Semantic equality hit:void test_arrays(Arrays*, const char*)->void test_const_volatile_arrays(ConstVolatileArrays*, const char*) So we'll get less warnings than expected.
