istringstream cannot read integers on Solaris 2.5.1
>How-To-Repeat:
$ cat t.cc
#include <iostream>
#include <sstream>

using namespace std;

int main(int argc,char *arv[])
{
 int i;
 istringstream offsets("1   4   0");

 offsets >> i;
 cout << i << endl;

 return 0;
}
$ g++ -o t t.cc
$ ./t
Segmentation fault

>Fix:
Do the same on Solaris 2.7 ;-) or use gcc-3.0.x
