Re: vector::pop_back issue

at the time class destruction, application error occurs. Seems
the heap was corrupted with the pop_back operation on empty
vector.

the code failed to execute in Visual C++ 6 and 2008. but
worked fine in DevCPP. I admit that the pop function should
check for empty vector. but still the different behavior
concludes, it's a bug in Microsoft STL Implementation

Or rather, that you've undefined behavior in your code. Garbage
in, garbage out, as they say. (From a quality of implementation
point of view, of course, the code should crash, at least in
debug mode. Which is what all of my implementations -- Sun CC,
g++ and VC++ -- do, once I fix the errors which prevent it from
compiling.)
