Anything I can do about this? What does this assertion mean?
My setup: Linux 64Bit, gcc 4.2.4, serialization is used for polymorphic objects loaded from different shared libraries, shared libraries are loaded with dlopen(RTLD_GLOBAL|RTLD_LAZY).
Assertion (extended_type_info.cpp:92) occurs during program termination (after main returned), during dlclose().
If anything else isn't possible, would it be appropriate to change the related code (before the release!) from:
assert(start != end);
// remove entry in map which corresponds to this type do{ if(this == *start) x.erase(start++); else ++start; }while(start != end);
After looking at this code again I have the impression that it is broken anyways. You can't safely increment an iterator after deleting the object it points to: erase(start++). This code relies on the fact that in order to be incremented the iterator doesn't need the object it points to (which at least for lists is a wrong assumption). Regards Hartmut
To:
assert(start != end);
// remove entry in map which corresponds to this type while(start != end) { if(this == *start) x.erase(start++); else ++start; }
Which wouldn't remove the problem, but at least avoids hanging the program if assertions are off...
