===============================================================
Windows98
gpp : GNU C++ version 2.95.3 20010315/djgpp (release) (djgpp)
      compiled by GNU C version 2.95.3 20010315/djgpp (release).
===============================================================

Here is a program that contains an error (index > string's size).

Because the at() method is used then
  * if pos < size(), returns the element at position pos in this string.

  * otherwise, an out_of_range exception is thrown

However the error report doesn't contain
  file name and line number of erroneous situation.

Is the any possibility to localize the error place ?

// ############# C++ Code : BEGIN #############
// File aaa.c

#include <string>
int main ()
{
string s1 ("ABCDE");
  s1.at(9) = 0;  // Here is an error : index must be < 5
  return 0;
}

// ############# C++ Code : END ###############
