glibc 2.2.2
The following code prints 12345 rather -3e-20 on glibc 2.2.2 (i.e. RedHat 7.1 and Suse 72).

#include <string>
#include <iostream>
#include <sstream>

int main() {

  std::istringstream iss("-3e-20");
  double ret= 12345;
  iss >> ret;

  std::cout << ret << "\n";

Please close 9527, because it is a duplicate having an incorrect synopsis.

Upgrading libc on redhat71 is a workaround. On suse72 there is no updated libc available.

In the releasenotes is a statement missing what glibc is required for gcc.
compile and run gcc-3.2.1 on an unpatched redhat71 or suse72.
