Cannot set breakpoints within debugging session windows 64bit cdb

Steps to reproduce:

• use a simple Qt GUI application (use MSVC/CDB)
• start the Debugger
• set breakpoint(s) that can be hit
• interact with the application to hit the breakpoint

Expected result:

• Debugger stops at the breakpoint(s)

Current result:

• Debugger seems to fully ignore the breakpoints

Additional information:

• If there are already some breakpoints set when starting to debug these breakpoints will be hit by the debugger and it stops execution.
• If you put more breakpoints into the debugged application - the additional breakpoints will make the debugger stop only if the debugger has stopped already on breakpoints that have been set before starting to debug.

All things mentioned above work fine, if I'm using MinGW/GDB instead of MSVC/CDB.
