Type: Bug
Resolution: Done
Priority: Not Evaluated
Fix Version/s: None
Affects Version/s: Qt Creator 2.3.0
Component/s: Debugger
Labels:
- beta230
Environment:
Windows 7, 64 bit
using
MS VC 2010 Express (x86) compiler
Debugging Tools for Windows (64 bit)

Qt version: 4.7.4

Steps to reproduce:

Create mixed QML/C++ , set BP on empty line in main.cpp
Run into breakpoint: Debugger stops, state is not set correctly (all icons disabled)

Note: Seems to be related to startup situation, see attached (debug.log).

Reproduced with CDB, g++, Linux, windows.

Debugging cannot be done when setting a breakpoint directly on the main().
This only happens when the QML debugging is enabled.

The buttons (and also the menu items) for "step over", "step in" and so on aren't enabled, so debugger seems to hang

Actually I only can use a work-around for that:
1. on the Application Output: attach debugger to this process
2. now you can press either "step in" or "step over" (no matter which one) - then this process seems to hang too
3. now go to Menubar->Debug->Abort Debugging and "normal" debugging should work

CDB debugger output:
