It works for me on RHEL 4 with gcc 4.4.1:

[hjl@gnu-14 tmp]$ cat foo.cc
#include <fstream>

using namespace std;

void f(const char * filename)
{
 ifstream is;
 throw 2;
}

int main()
{
 try {
  f("v3");
 } catch(int e) {
 }
}
[hjl@gnu-14 tmp]$ /usr/gcc-4.4/bin/g++ foo.cc -Wl,-rpath,/usr/gcc-4.4/lib
