Sorry, but I don't understand what you mean.
I'll take a concrete example of faulty code that STLPort in debug mode 
will detect and give useful diagnostics on.
I would also like to get such diagnostics when using gcc without STLPort.
In my experience the following program will cause a Segmentation fault.:

#include <vector>
#include <iostream>

int main(){
  std::vector<int> v;
  std::cerr << v[2];
  return 0;
}
