Please submit a full bug report.
See <URL: http://www.gnu.org/software/gcc/faq.html#bugreport > for instructions.

Very simple program that caused it:

#include <iostream>
#include <vector>
using namespace std;
class class_1 {};
class class_2 : public class_1 {};
void main() {
    vector<class_1 &> input;
    input.push_back(*new class_2());
}

Appears to be connected with some kind of memory leak as compiler appears to correctly bail out some times; other times I get the above internal error. I think it could be connected with too many error messages being generated. Hmm. Lemme know. Sorry I can't help fix this or even verify it better.

Hopefully someone out there will at leat be able to duplicate it.

I don't need it fixed. It's just that if this error exists, perhaps it's caused by a larger bug.

If I use -O, message appears to go away.
>How-To-Repeat:
Using Windows ME, go to the command prompt and run the following command:
gcc -c qd__gcc__bug.ii

Because of the possibility that this is connected to memory leaking, I advise creating a _NEW_ DOS command prompt and IMMEDIATELY compiling the above file, rather than first compiling something else etc. Dunno.
