[swift-users] EXC_BAD_ACCESS on iOS simulator at app launch

[Ramakrishna Mallireddy]

I compiled clang, llvm and swift static libraries for iOS.

I created default single-page view ios swift project, added
frontend_main.cpp and an objective c wrapper with a single method that
calls frontend_main. I added the bridge header and when run on iOS
simulator i got EXC_BAD_ACCESS.

I have not even called any methods of the libraries yet.

The control never reached the AppDelegate.

below is the* backtrace*:

* thread #1: tid = 0xc25cb, 0x0d1ffddb
libsystem_pthread.dylib`_pthread_rwlock_check_init + 11, queue =
'com.apple.main-thread', stop reason = EXC_BAD_ACCESS (code=1, address=0x0)

Does anyone have any idea what gone wrong.
