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

[Michael Jackson]

Using Xcode 5.1.1 for our project and setting the exact same break point in the code does not exhibit this issue so I am pretty positive that this is an issue with the QtCreator<-->LLDB integration somehow.

What do I need to report back to QtBug reports to get this looked at? It really breaks the ability to debug our codes. This was with LLDB version lldb-310.2.37 on OS X 10.8.5 (Xcode 5.1.1 tooling). I also tried LLDB 3.6 on Ubuntu 14.04 and while the memory load did not happen, LLDB spun for a bit then just crashes.

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.
