Every time I try to run my target when Breakpoints using the LLDB Debugger, Xcode crashes. My colleague has no trouble using LLDB, and we\'re both running 4.4 (I\'ve had the

We recently fixed some name demangling issues. The name demangler is built into the OS in libc++abi.dylib. You can build this yourself and install it to possibly fix your issues:

% sudo cp /usr/lib/libc++abi.dylib /usr/lib/libc++abi.dylib.orig
% svn co http://llvm.org/svn/llvm-project/libcxxabi/trunk libcxxabi
% cd libcxxabi/lib
% TRIPLE=x86_64-apple-macosx ./buildit
% sudo cp libc++abi.dylib /usr/lib/libc++abi.dylib

You can also just "try it out" without installing the "libc++abi.dylib" to make sure it fixes things first. The steps for that are:

Quit Xcode first, and then:

% svn co http://llvm.org/svn/llvm-project/libcxxabi/trunk libcxxabi
% cd libcxxabi/lib
% TRIPLE=x86_64-apple-macosx ./buildit
% DYLD_LIBRARY_PATH=`pwd` /Applications/Xcode.app/Contents/MacOS/Xcode

This will run Xcode and allow it to use the local copy of "libc++abi.dylib" that you just built.
