Running iOS Unit Tests from Command Line with Xcode 4.5

While running Unit Tests from command line (necessary for Jenkins) used to work until Xcode 4.4.1 with this hack, it does not seem to work anymore with Xcode 4.5.

Now I get the following error message:

....MyTests.build/Script-641C6E0115D3BECD004175F...: line 3: 16669 Segmentation fault: 11  "${SYSTEM_DEVELOPER_DIR}/Tools/RunUnitTests"

Any ideas how to make it work again?
