[Qt-creator] LLDB consumes large amounts of memory (Multi Gigabytes)

We are trying to use the LLDB debugger under OS X 10.10.5 with Xcode 6.4 for our project. When using the QtCreator 3.5 release and attempting to stop at a break point LLDB spins up to 100% CPU and eventually uses all the memory on the machine (About 8 GB). I eventually have to force quit LLDB and basically can not debug. The version of LLDB that comes with Xcode 6.4 is 330.0.48. 

Has anyone else seen this problem with QtCreator? If I generate the same project as an Xcode project then I have no problems stopping at breakpoints and no memory issues.
