Description
Running this code:
#include <QtGui/QGuiApplication> #include <QtQml/QQmlEngine> int main(int argc, char **argv) { QGuiApplication app(argc, argv); QQmlEngine engine; return 0; }
results in a segmentation fault on powerpc:

I am happy to provide any other debugging information if needed.
The same happens on mips, which is also a 32-bit big endian architecture.
