            Bug ID: 485675
           Summary: lambda-in-connect does not honor receiver context
    Classification: Developer tools
           Product: clazy
           Version: unspecified
          Platform: Other
                OS: Linux
            Status: REPORTED
          Severity: normal
          Priority: NOR
         Component: general

  Target Milestone: ---

Created attachment 168616
  --> https://bugs.kde.org/attachment.cgi?id=168616&action=edit
patch to show failure in unit test

SUMMARY
lambda-in-connect seems smart enough to figure out if the sender is in the same
stack frame as a capture, but does not take the receiver context into account

STEPS TO REPRODUCE
See attached patch

OBSERVED RESULT
```
        QObject o2;
        QObject::connect(&o2, &QObject::destroyed, [&m]() { m; }); // OK, o2 is
on the stack

        QObject *o3;
        QObject::connect(o3, &QObject::destroyed,
                         o3, [&o3] { o3; }); // OK, the captured variable is on
the 3rd parameter too. It will get destroyed

        // this fails:
        QObject::connect(o3, &QObject::destroyed, &o2, [&m]() { m; }); // OK,
o2 is on the stack
```

EXPECTED RESULT
failure for constructs such as the last one, where `m` is on the stack and gets
destroyed after `o2`.

SOFTWARE/OS VERSIONS
latest clazy master against clang 17.0.6
