Description
Building a C++ library that uses QAtomicInt decrement for iOS fails (note: iOS simulator and OSX desktop kits for the same project are fine). Also note that using the 'app' template in qmake seems ok but not the 'lib' template.
Steps:
1. QtCreator -> New Project -> Library -> C++ Library (iOS kit)
2. Use atomic int decrement
Qt_ios_static_lib::Qt_ios_static_lib()
{
QAtomicInt foo(99);
--foo;
}
3. Try to compile
