Xcode 4.3 crashes when using LLDB - xcode

Question

Since installing xcode 4.3 (from the app store), Xcode crashes when I try to run a few of my apps with the debugger set to LLDB. GDB works fine.
I've already tried reinstalling iTunes and removing all traces of xcode and reinstalling that. I've also tried removing the .xib files and re-adding them to the project.
Any help would be great :)
Here is some of the report that is generated:

Answer 1

Hi I have the same problem and I reported to Apple, they told me is a bug and they know about it , my only way around is to change the compiler to GDB all the time, until Apple fix the bug.

Answer 2

I have solve the problem as bellow:may be is useful for you.I try to execute the lldb command in terminal, it got the result like that the my lldb need the python 2.7.but before,when i install the clang,the python version changed to 2.6,so i reinstall the python 2.7.my lldb worked well.

Answer 3

Have you upgraded to Xcode 4.6.1? If so then look for /System/Library/Frameworks/Python.framework/Versions/2.7 if there is no 2.7 reinstall Python. There is a installer at Python.org for MAC. Btw if you happen to see Current and not 2.7 remove the folder called Current. I had the LLDB problem and this is what I've done and everything worked well.

Answer 4

I had a same problem when Python was installed with homebrew.
I just did this:
sudo ln -s /usr/local/Cellar/python/2.7.6/Frameworks/Python.framework/Versions /System/Library/Frameworks/Python.framework/Versions
And problem was solved.

Answer 5

Still isn't working for me as of Mountain Lion (10.8.2), Xcode 4.5.1, I've tried deleting and reinstalling to no avail. This isn't a huge deal to me right now as I'm still learning (did the Stanford course & doing the Big Nerd Ranch book right now) however I imagine once I start doing some team work that people won't appreciate me changing the Product Scheme over from LLDB to GDB just so I can run the simulator.
