bug in gcc? in STL? <list> collides with my operator overloading

[Andreas Krueger]

Hello,

I have found a very peculiar problem in g++
which I can't solve. Perhaps it's even an STL-bug or gcc-bug?
I need help.

I have written a (template) container "measure" to hold
 a +/- b
 (for error propagation)
with lots of operator overloading.
It is part of a bigger physics project, but here I mention just the actual
problem of porting it to unix.

Everything works fine, the class is tested in many situations,
BUT:
As soon as I   #include <list>
I get very strange errors on gcc (version 2.95.2),
concerning    /usr/include/g++/stl_iterator.h
 -> www.andreask.de/cpp/measure/gcc-errors.txt

If I don't use a STL-container like <list>
or if I use M$ Visual-C++, I have
no problems at all.

Please have a look at this.
When you un-comment the second line - the trouble starts.

#include <iostream>
// #include <list>            // here is the problem
#include <math.h>
#include "measure.h"

void main(){
 typedef measure<double> measure;
 measure a=measure(2,0.1);
 test_measureclass();
 interactive_test_measureclass();
}

You can find my class "measure.h" at:
 -> www.andreask.de/cpp/measure/measure.h
and the (above) test program at:
 -> www.andreask.de/cpp/measure/gcc-test.cpp


What can I do? What code is wrong?
Need the STL or g++ be changed?
Can you think of a workaround?

Thanks a lot in advance.
ciao,
Andreas
