You're right.

To be clear: as per Qt terminology, QRegExp is reentrant, not thread-safe.

That means you can use QRegExp in different threads, at the same time, provided 
that they point to different objects. If it's the same object, do as Milian 
said.

It's easier to just create a copy in this case.
