local static QMutex

This will seem to work fine too however is completely incorrect and some day when you least expect it will explode in your face:

QString x = "abc";
printf("%s\n", x.toLocal8Bit().constData());

QString x = "abc";
printf("%s\n", x.toLocal8Bit().constData());

Sorry, it's no argument for me that something "works".

By the way, this will also "works" most of the time:

int x, y; // uninitialized
int z = x/y;

int x, y; // uninitialized
int z = x/y;
