Not as a general way, but it's been a requested feature for
QRegularExpression to be able to save/restore the bytecode. While I
can tell the users to never restore from untrusted data, my question
was about data saved from PCRE itself -- that is, if it's guaranteed
to work in any case (this includes rejecting loading, important bit is
not to crash), especially using a platform for saving and another
platform for loading.
