Confirmed.
I'm still reducing the testcase, however.
Down from 56k lines to 15k lines now. :-(
I'll post it when I have something more reasonable.

Created an attachment (id=6540)
--> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=6540&action=view)
still large testcase
I give up for now. I managed to get the testcase down to 6000 lines
and only one include file, namely <vector>.
I attached the whole preprocessed stuff (which is about 15000 lines).
In case somebody wants to factor out the include file, just
replace everything before the function "toss_cookies" by the
include file.

Fixed on lno-branch by Zdenek's patch.
Zdenek, will your patch soon be seen in mainline, too?
(The problem is a regression on mainline.)
What about a testcase for the testsuite?

It seems to be fixed on both lno and mainline as of today (Jun30) - but I cannot
find traces of the patch that went into lno on mainline.
Is the patch still needed on mainline?

The patch was never reviewed, this is why it didn't go into mainline yet, but
it's still needed there I suppose, even if the bug cannot be reproduced with
this testcase anymore.

yes, the patch is still needed, even if the problem was masked by some
other commit.

I still (20040701) get an ICE on mainline with Serge's testcase as well
as with the following one (just compile with "gcc -O2 -funroll-loops"):
============================
int foo();
int bar(int i)
{
int j = foo();
i /= 3;
while (j) ++j;
return i;
}
============================
