cppcheck 2.10: false positive interaction between [shadowFunction] and Q_EMIT

[Sylvain Joubert]

In Qt code, any (if not all) lines using the Q_EMIT macro:

Q_EMIT mySignal(42);

now trigger a shadowFunction warning like:

warning: Local variable 'mySignal' shadows outer function [shadowFunction]
  Q_EMIT mySignal(42);

I see a specific line to define the emit macro in qt.cfg (which I'm using) but nothing about Q_EMIT. I've been able to fix the issue locally by using a custom config file with the following content:

<?xml version="1.0" encoding="UTF-8"?>
<def format="2">
  <define name="Q_EMIT" value=""/>
</def>

This should probably be added to the qt.cfg

[Oliver Stöneberg]

How do you load the library? Which command-line do you use?

Could you also provide a full code sample which triggers the warning?

Thanks.
