xxx$UNIX2003 -> springboard_unimplemented crash

I have an iOS project that worked fine under earlier version of XCode.

After upgrading to XCode 3.2.6 it stopped working and crashes with SIGABRT signal when I try to execute it under simulator.

Crash happens when the application is trying to invoke pthread_rwlock_wrlock.

Crash stack (reversed) is:

MyAppFunction

pthread_rwlock_wrlock$UNIX2003

_springboard_unimplemented

abort

raise

kill$UNIX2003

_kill

At the point of crash the following message is emitted to debugger console:

"Detected an attempt to call a symbol in system libraries that is not present on the iPhone: pthread_rwlock_wrlock$UNIX2003 called from function MyAppFuncton in image MyAppImage."

I have selected BaseSDK as "Latest iOS (iOS 4.3)" in project settings, which is the only iOS SDK version available in the list.

ActiveSDK is set to "Simulator".

No matter what version of simulator I choose for debugging (from 3.2 to 4.3) the result is the same: crash as described.

Please advise.

XCode-OTHER, iOS 4.3

I am not sure what you were trying to say, KT.

Follow that goggle link.

Note:

pthread_rwlock_wrlock

The pthread_rwlock_wrlock() function applies a write lock to the read-write lock referenced by rwlock. The calling thread acquires the write lock if no ...

...there are several more. Study them for references that may pertain to your specific issue. I doubt it has anything to do with basic app settings/configuration.

What do you have the Build iOS Deployment Target set to?

Deployment target is set to iOS 4.3.

I tried right now setting it to iOS 3.2 and rebuilding, but it changed nothing.

KT, my specific issue is that pthread dynlib ceased to be loadable with the app after XCode upgrade, and references to DLL linkage vectors are replaced by abort intercepts at load time. This has nothing to do with man pages for function APIs.

Use Applications>Utilities>Console to look at the Xcode install log and check for errors. Re-install if needed.

Also, try rebooting your Mac.
