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

[degraaf at cpsc dot ucalgary dot ca]

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

Preprocessed source for bug 17220

Compile with -fomit-frame-pointer, and it fails.  Compile without, and it
works.

Confirmed with -march=i386 -fomit-frame-pointer so this is a target problem.

I could reproduce the patch previously, but after
  http://gcc.gnu.org/ml/gcc-patches/2004-11/msg02219.html
and
  http://gcc.gnu.org/ml/gcc/2004-11/msg00912.html
I can't.

This may mean that it was a duplicate of PR6764, though I can't prove
that from the Rather Large-ish test case.

Closing as fixed as I can no longer reproduce it either but I could before.
