Steps to reproduce:
1. Create a file error.cpp containing
class Foo
{
public:
Foo* myMethod(Bar bar);
};
2. Compile with
$ gcc error.cpp
Expected Results:
error.cpp:4: error: type Bar is undefined.
Actual Results:
error.cpp:4: error: expected ; before ( token
Notes:
The error message is wrong and misleading.
