I now think this is more likely this problem instead:

http://sources.redhat.com/ml/binutils/2004-02/msg00003.html

The bug is present using at least Cygwin/gcc 3.3.3 and MinGW/gcc 3.2.3.

It was a bitch to check if MSVC is affected. The test bugged out
earlier and was terminated before the interesting part.

I really think stresstest.at should be broken up in more tests. As
is, it is PITA to debug problems found by it. Appart from the
difficulty in seeing exactly what went wrong, it is also not
possible (?) to skip ahead to the test you're interested in which
is a big waste of time. It would be valuable to run all tests (or
at least more tests) even if some of them fails.

Anyway, after rearranging the loops so that '-export-symbols asyms'
is first in the l2 loop and '-rpath /nonexistent' is first in the
l3 loop, I see that this bug is not present with MSVC.

I should upgrade to gcc 3.4 or 4 and see if the problem goes away...

Cheers,
