This popup prevent other scripts from running and prints the following:

instruments[2596] : kCGErrorInvalidConnection:
CGSGetCurrentCursorLocation: Invalid connection instruments[2596]
: kCGErrorFailure: Set a breakpoint @ CGErrorBreakpoint() to
catch errors as they are logged.

Segmentation fault: 11

I use subprocess (in python) to run number of scripts for testing my app.

Is it a bug in instruments? cause sometimes it just print to log a debug event: "The target application appears to have died", which doesn’t stop scripts flow.

Any ideas?

[Edit]

I’ve updated yesterday command line tools and it seems to provide more details now:

    You need to use the .app file in the iPhone simulator directory.

    (or)

    Do an xcodebuild with DSTROOT flag to deposit the app and use that for the automation.

    xcodebuild -workspace ./ProjectWorkspace.xcworkspace -scheme "SchemeName" -sdk 
iphonesimulator5.1 -configuration "Debug" clean build install 
DSTROOT=~/Desktop/tmp/yourAppName.app
