qApp->processEvent() cause crash

[songnailiang]

There's one confused err in my code.
pseudo code as follows:

connect(mysignal, myslot);
connect(mtsignal_2, myslot);

void myslot(QString msg)
{
textEdit->append(msg);
qApp->processEvents(); //if comment this line, no crash, but other function also use this to prevent UI hang
}

void func()
{
for(i=0;i<n;i++)
emit mysignal;
}

[problem] when i increase to some fixed value, exe crash, err stack overflow in ntdll.dll

how to solve this bug?
Thanks in advance!

Why would you even want to call that in there?

Calling qApp->processEvents() only makes sense in the middle of a long-running computation ; it is useless just before control returns to the event loop, as is the case here.
