QtCreator 17.0.1 Debugger: Incorrect display of QHash<qlonglong, T> and limited variable nesting depth

[Tetsuzin72]

Hello,

I'm experiencing issues with the debugger in the new QtCreator 17.0.1 compared to the older version 8.0.2. My environment is Windows 10 with Qt 5.12.3 and the debugger from the latest Windows SDK.

I have two specific problems:

Incorrect display of QHash<qlonglong, SomeType>: The qlonglong keys are displayed incorrectly (with wrong values or type interpretation) in the Locals and Expressions window in QtCreator 17.0.1. The same variable is displayed correctly in version 8.0.2.

Limited variable nesting depth: The debugger in the new version does not display elements deeper than 4 levels of nesting. The old version correctly shows the full structure without such limitations.

I have attached two screenshots for comparison. The first one shows the correct display in QtCreator 8.0.2, and the second one shows the problematic behavior in QtCreator 17.0.1.

Has anyone encountered similar issues? Is there a known fix or a setting I might have missed?

Thank you for your help.!
