[Bug libstdc++/42242] vector::resize unnecessarily calls null constructor

[redi at gcc dot gnu dot org]

------- Comment #1 from redi at gcc dot gnu dot org  2009-12-01 18:21 -------
this is caused by the default argument to resize:

void
resize(size_type __new_size, value_type __x = value_type());


It would be possible to avoid the default construction by replacing that member
with two overloads of resize, but I'm not sure it's worth doing.
