Discussion:
In C++1x (N3090) there are two version of vector::resize — 23.3.11.3 [vector.capacity]:
void resize(size_type sz); void resize(size_type sz, const T& c);
The text in 23.3.11.3 [vector.capacity]/12 only mentions "no effects on throw" for the two args version of resize:
Requires: If an exception is thrown other than by the move constructor of a non-
CopyConstructibleTthere are no effects.
This seems like unintentional oversight since resize(size) is
semantically the same as resize(size, T()).
Additionally, the C++03 standard only specify single version of resize
with default for the second argument - 23.2.4:
void resize(size_type sz, T c = T());
Therefore not requiring same guarantees for both version of resize is in fact a regression.
