QProcess assert crash with setStandardOutputProcess

setStandardOutputProcess fails to work as intended and results in the following assert error

ASSERT: "channel->pipe[0] != INVALID_Q_PIPE" in file io\qprocess_win.cpp, line 561

Example:
QProcess *p1 = new QProcess();
QProcess *p2 = new QProcess();

p1->setStandardOutputProcess(p2);
p2->start("bleh");
p1->start("heh");
