SIGABRT when running tests

When running standard tests (passed in the path of the test folder to main) I get a SIGABRT on line 130 of typeSamplers.cpp, and can't work out why. Changing assignment to another string gives the same result. Here is the stack trace:

Looks like the project files had some preprocessor macros defined that were causing havoc with the more recent STL in Xcode 4.5. I did some cleanups of the project files, and as of commit 6e7b8cd the crash seems to be gone with Xcode 4.5.
