This looks a lot like bug #15069, which was marked fixed for 3.4.1 (as far as I
can tell - I'm new to GCC Bugzilla). However, I'm using GCC 3.4.1 on linux, and
I'm seeing a problem with the code:
#include <iostream>
using namespace std;
// atom type
enum eAtomClassification {
eSideChainAtom,
eAlphaBackboneAtom,
ePartialBackboneAtom,
eCompleteBackboneAtom,
eUnknownAtom
};
int main(int argc, char **argv)
{
eAtomClassification classification = eUnknownAtom;
if ((classification == eAlphaBackboneAtom) ||
(classification == ePartialBackboneAtom) ||
(classification == eCompleteBackboneAtom))
{
cout << "error:\n";
cout << "class " << classification << "\n" << flush;
cout << eAlphaBackboneAtom << " "
<< ePartialBackboneAtom
<< " " << eCompleteBackboneAtom << "\n" << flush;
return 1;
}
cout << "okay\n";
return 0;
}
When compiled with optimization, it doesn't execute properly:
(trans)(~/tmp) g++ -O1 -o gcc-bug-2 gcc-bug-2.cpp
(trans)(~/tmp) gcc-bug-2
error:
class 4
1 2 3
(trans)(~/tmp) g++ -O2 -o gcc-bug-2 gcc-bug-2.cpp
(trans)(~/tmp) gcc-bug-2
error:
class 4
1 2 3
(trans)(~/tmp) g++ -O0 -o gcc-bug-2 gcc-bug-2.cpp
(trans)(~/tmp) gcc-bug-2
okay
Is this the same bug #15069, or is it something different? In any case, it's not
working in 3.4.1... My version:
(trans)(~/tmp) g++ -v

This is indeed fixed on the 3.4 branch, while it still exists in
mainline. That's the same as the bug to which it was marked as
a duplicate.
