The following program compiles without error:
#include <iostream>
#include <string>
std::string f() {} main(){ std::string s(f()); return EXIT_SUCCESS; }
The function f() does not return a value, string s is filled with random areas
of memory. The program segfaults. gcc -v output from my machine (I tested
this on a few others):
[EMAIL PROTECTED] ~/temp $ gcc -v
