    <p>So I've gotten LLDB working in Xcode with <a href="https://stackoverflow.com/questions/11905378/xcode-4-3-4-4-crashes-with-breakpoints-using-lldb-breakpoints-useless-with-gdb">this solution</a>. Now however whenever I try to edit a breakpoint within Xcode, I get a crash. You can see from the backtrace of the crashed thread, frame 7 and 8 points towards the libc++abi.dylib possibly being involved. Manipulating breakpoint objects form the console of LLDB seems to work just fine</p> <p>Here's the crash log:</p> <pre><code>Process: Xcode [21079] Path: /Applications/Xcode.app/Contents/MacOS/Xcode
