I can confirm that the problem is still present on k6.
According to Phil's tester the problem for the ix86 was fixed
between 2003-01-31 and 2003-02-01.
Therefore I strongly suspect that the following patch (by Richard
Henderson and Falk Hueffner) was responsible for the fix:
http://gcc.gnu.org/ml/gcc-cvs/2003-02/msg00033.html
That's why I'm asking you, Richard and Falk, could you please
have a look at the patch, whether it really did fix things and if yes,
why it doesn't fix the k6-issue and whether the fix can be backported
to 3.3 or even 3.2?
Thanks,
Volker
