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
$
$ g++ -v

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.
