CDB very slow under some conditions



  • Hello,
    I take the MSVC2012-32 compiler and debug with the QtCreator.

    When I drop a local variable onto the "Locals and Expression" panel the stepping from line to line take about 30 seconds to minutes.
    In the Taskmanager I see that "Symbolic Debugger for Windows (32-bit) uses 17% CPU for my 8-Core-System. This seem to be the reason !?
    What can I do ?

    Another effect, dropping a second variable to this panel during runtime changes nothing. Only a restart updates the panel. Is this a bug or a feature :-) ?

    From my experience cdb sucks quite badly, so I don't think it's really a Qt/QtCreator problem. From what I can tell it crawls to a stop when a big object's fields have to be listed, but unfortunately I don't know any workarounds for it.

    Another effect, dropping a second variable to this panel during runtime changes nothing.

    Probably the debugger simply hangs and the panel is not updated at all, but I'm speculating here.
