[Bug c++/17220] New: Incorrect ouput for C++ exceptions with -fomit-frame-pointer

["degraaf at cpsc dot ucalgary dot ca" <gcc-bugzilla at gcc dot gnu dot org>]

The following code compiles and executes correctly when compiled without
-fomit-frame-pointer, but aborts when compiled with -fomit-frame-pointer:

$ cat registry.cpp
#include <map>
#include <string>
#include <iostream>
using namespace std;

class Registry 
{
  public:
    Registry() : reg() {}
    ~Registry() {}
    void getFloat(string key)
    {
        map<string, float>::iterator i = reg.find(key);
        if (i == reg.end())
            throw new int(5);
    }

  protected:
    map<string, float> reg;
};

int main()
{
    Registry reg;
    string s = "four";
    
    try 
    {
        reg.getFloat(s);
    }
    catch (...)
    {
        cout << "caught one" << endl;
    }
    return 0;
}

$ g++ registry.cpp
$ ./a.out
caught one
$ g++ -fomit-frame-pointer registry.cpp
$ ./a.out
Aborted
