<pre>
    I  have this code:

`struct AnInterface {};`

`typedef AnInterface ABase1;`
`class AClass1 : public ABase1 {};`

`typedef AnInterface ABase2;`
`class AClass2 : public ABase2 {};`

And this ASTMatcher:

`cxxRecordDecl(`
`  isDerivedFrom(`
` decl().bind("typedef")`
`  )`
`).bind("record")`

The second match wrongly binds `AClass2` and **`ABase1`**.
The same behavior occurs with
`using ABase1=AnInterface`

Output of clang-query:

> clang-query> m cxxRecordDecl( isDerivedFrom( decl().bind("typedef") ) ).bind("record")
> 
> Match #1:
> [... works as expected]
