I’ve
downloaded recently the version Boost 1.34.1 and performed some tests on ours
applications integrating Boost components.
During
theses tests, I’ve tried to deserialize some XML
archives generated w/ Boost 1.33.1 including some boost::optional<> instances and I’ve observed that
the Visual C++ 7.1 IDE emits run-time checks in the load<boost::optional<>>()
@ line 60 in file
boost/serialization/optional.hpp.
template<class
Archive, class T>
void
load(
Archive & ar,
boost::optional<T> & t,
const unsigned int
/*version*/
){
bool tflag;
ar >> boost::serialization::make_nvp("initialized", tflag);
if (tflag){
unsigned int
v;
if(3 < ar.get_library_version()){
ar >> make_nvp("item_version",
v);
}
detail::stack_construct<Archive, T>
aux(ar, v);
^^^^^^^^^^^^^^^^^^^^^^^^
Here
Run-Time Check Failure #3 - The variable 'v' is being used without being
defined.
ar >> boost::serialization::make_nvp("value", aux.reference());
t.reset(aux.reference());
}
else {
t.reset();
}
}
Is it
possible to avoid this run-time check by a preinitialisation of the local variable “v”? Is it a Bug?
