3037,assert and later crash on app shutdown if BOOST_CLASS_EXPORT is used in headers,Marvin.Sielenkemper@…,Robert Ramey,"The extended_type_info is registered multiple times if a header bound BOOST_CLASS_EXPORT is included in multiple implementation files. Each of these registrations enters the same type info object into a (multi-)map.

On shutdown only the _first_ unregistration removes _one_ object from the map and clears its key member. Since there are still pointers pointing to this object in the map, later unregistrations fail due to the invalid key.

The problem can easily be fixed by either removing the ""break;"" in the unregister function (thus keeping the multiple equal pointers in the map) or adding ""if (m_key) return;"" in the register function (thereby collapsing the multiplicity to one).

I have created a test to trigger the problem, patch follows.",Bugs,closed,Boost 1.40.0,serialization,Boost Development Trunk,Problem,fixed,,
