--- Comment #1 from John Colvin <john.loughran.colvin at gmail.com> ---
I suspect this is the same bug, seeing it's the same error in similar
circumstances regressed across the same release.

This worked fine in 2.072.2 and now fails in 2.073:

ref int foo(return ref int s)
{
    return s;
}

int fail()
{
    int s;
    return foo(s); // Error: escaping reference to local variable s
}

int ok()
{
    int s;
    s = foo(s);
    return s;
}


Changed to regression because it's broken correct code.
