There are two cases, either you get an error message that is wrong, and you can
use:
strncpy (p, s, 60); /* { dg-bogus "-Wstringop-truncation" } */
or, you don't get an error, but you should:
A foo(void i = 0); // { dg-error "incomplete type|invalid use" }
? Do you have an example of a specific case that doesn't work? I'm not sure
I'm following.
