------- Comment #4 from pinskia at gcc dot gnu dot org 2006-01-09 16:24 -------
Here is the testcase from the tar ball for us lazy people:
#include <iostream>
#include <sstream>
using namespace std;
int printit(const char * const str) {
return *str;
}
int main()
{
ostringstream ostr;
ostr << "test test test" << ends;
const char * const str = ostr.str().c_str();
printit(str);
return 0;
}
-----
ostr.str() returns a temporary variable which dies right after the end of the
statement which means that the return value of c_str() becomes invalid after
the statement finishes.
This is exactly what Paolo said in comment #2.
