clearly its a bug but it shouldn't affect any programs, I'll fix it in my working copy. You can fix it by just initializing to 0.

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?
Best regards,
Used Configurations:
Windows XP
Boost 1.34.1 (through Boost Installer w/ DLL libraries)
