This code does not compile in clang-9 (as of 2019-03-21):

void foo() 
{
    int i = 42;
    try {
    }
    catch(...)
    {
       int ref = i;
       {
           int ref = i;
       }
    }
}


<source>:10:16: error: redefinition of 'ref'
           int ref = i;
               ^
<source>:8:12: note: previous definition is here
       int ref = i;
           ^
1 error generated.

Compiler returned: 1
