            Bug ID: 376137
           Summary: Internal error caused by overloaded signal
           Product: clazy
           Version: unspecified
          Platform: Other
                OS: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: unassigned-bugs at kde.org
          Reporter: daniel at pfeifer-mail.de
                CC: smartins at kde.org
  Target Milestone: ---

Here is the code to reproduce it:

#include <QObject>

class Foo : public QObject
{
    Q_OBJECT

public:
    Foo()
    {
        connect(this, static_cast<void (Foo::*)(int)>(&Foo::bar), [](int) {});
        connect(this, qOverload<float>(&Foo::bar), [](float) {});
    }

Q_SIGNALS:
    void bar(int);
    void bar(float);
};


Currently, both connect calls produce "internal error: couldn't find method
from pmf connect".

Once this is fixed, you may think about adding a checker that flags the use of
static_cast in signal connections and recommends to use qOverload.  Thanks!
