This is not the first time that I encounter this problem, but I will take this opportunity to quickly post it now that I have it at hand.
Sending bt to the Debugger returns this during a debugging session:
#0 RWProperty<int, TBuilding, &(TBuilding::FGetCurrentFloorNumber() const), &(TBuilding::FSetCurrentFloorNumber(int))>::operator= (this=0x22fcbc, value=@0x22fcc8) at inc/Property.h:225
#1 0x0041535f in test () at C:\Programming\TestProperty\src\main.cpp:589
#2 0x00417624 in main () at C:\Programming\TestProperty\src\main.cpp:798
The call stack window only shows frames 1 and 2. Going to the next line seems to go to the right file in the right line, then it sends me back to the file and line in frame #1 (which is not where the debugger really is).
