Bug#137017: libstdc++3-dev: Included code for rope segment faults. Runs OK in v2.10

[Marc Singer <elf@buici.com>]

Package: libstdc++3-dev
Version: 1:3.0.4-1
Severity: important

The following code will segment fault with the installed libstdc++ and
g++-3.0.   It runs correctly on the 2.9x compiler with the v2.10 of
libstdc++.  Note that the substr line, a replacement for erase, also
fails with the 3.0 compiler.  


/* buffertest.cc

*/

using namespace std;

#include <stdio.h>
#include <unistd.h>
#include <ext/rope>

int main (int, char**)
{
  rope<char> r;
  char sz[] = 
    "Now is the time for all good men to come to the aid of their party.\n"
    "Now is the time for all good men to come to the aid of their party.\n"
    "Now is the time for all good men to come to the aid of their party.\n"
    "Now is the time for all good men to come to the aid of their party.\n";
  
  r.append (sz, strlen (sz));
  while (r.size ()) {
    printf ("%d\n", r.size ());
    r.erase (0,50);
    //    r = r.substr (50, r.size () - 50);
  }
  exit (0);
}
