QProcess instation has different behaviour when built for deploy and i't undocumented

QProcess *myProcess = new QProcess(parent);

if parent is a null pointer, it works fine, but when built for deploy this line of code will throw an error. There's no reason given in the documentation for the presence/absence of a parent object for Qprocess, and no indication given that anything should be different between debug and deploy build configs.

Recommend adding to documentation an explenation for the requirement of an actual parent object - or fixing the situation so behaviour is the same for debug/deploy builds - or indicating in documentation that there is some difference in behaviour between debugy/deploy
