Hello,

when debugging C++ member functions, variables that stand before a lambda function, tooltips do not work. I attached an example project.

Commenting the lamba function out, the tooltips for the variables work again.

• Global and member variables show "No valid expression",
• local variables show an empty tooltip
• In the "Locals-Window", all variables are shown correctly at any time

Variables that stand after the lamda can be "tool-tipped" without a problem,

As we use many lambda functions in our C++ project, this makes debugging much harder.

The general usage of tooltips was improved by much in this task: QTCREATORBUG-19574
