Memory leak of QLocalePrivate data when calling QString::num

Hi,

I noticed in the Qt 5.1.0 beta 1 debug version lots of memory leaks of 12 bytes of size. After some research I pin pointed the problem in the QString::num static method that uses a QLocale which has a leak on it's shared data QLocalePrivate. Didn't do too much research after that, I only created a small test that shows this leak:

int main(int argc, char *argv[])

{ _CrtSetDbgFlag(_CRTDBG_ALLOC_MEM_DF | _CRTDBG_LEAK_CHECK_DF); QString str = QString::number(14, 10); return -1; } In Visual Studio 2010 debug console: Detected memory leaks! Dumping objects -> {172}

normal block at 0x02385EF0, 12 bytes long.
Data: < G g > B0 47 1F 67 01 00 00 00 00 00 CD CD
Object dump complete.

I found something similar on the issue tracker at:
