Now I'm getting odd crashes when dealing with std::string objects. All of the strings that crash so far are static members of C++ classes. Some were being inited at launch. I changed that behavior to init them lazily, which fixed that. Now others are crashing during normal operations during run. Just wondering if anyone else has experienced problems with std::string in libc++ or anything like that. Note that we still need to use the 10.7 sdk. I'm not sure if using a newer one would make a difference - I tried, but there are a couple things that I couldn't change in a quick and dirty way just to get it building. This is Xcode 5.0.2.
My *guess* is that some of your code is compiled using libstdc++, and the rest with libc++.
They each have an idea of the layout of a std::string object, and they differ.
