GCC STL bound checking

How do I enable bound checking for operator[] and iterators?

Solution

  • You can activate runtime iterator and bounds checking by compiling with -D_GLIBCXX_DEBUG. Also note that random-access containers provide the always bounds-checking at()-operation in addition to operator [].
