Indeed, a couple of which could be considered serious:

- Issue #6573: set.union() stopped processing inputs if an instance of self
  occurred in the argument chain.

- Issue #6415: Fixed warnings.warn segfault on bad formatted string.

- Issue #6344: Fixed a crash of mmap.read() when passed a negative argument.


As a sidenote: I'm a relatively young core developer here, are there any
precedents of such critical bugs? How has the situation been handled
then?

Antoine.
