[Bug c++/30340] pure virtual function called on const & declared with previous declaration without a definition, const & assigned by temporary

[pinskia at gcc dot gnu dot org]

------- Comment #4 from pinskia at gcc dot gnu dot org  2007-01-01 05:42 -------
For the last question on this code:
    C c(1, B());

What is the life time of the temp that holds B()?

I say it is only for that expression and not for the lifetime of c so you are
now using a temp whos life time expired which means the behavior is undefined
and what GCC is producing at runtime is correct.
