Dirk & folks,
Could you please cut me from the Cc:? This is the twelfth entry in my
inbox, I'm leaving for Lisbon tomorrow, and I'm unlikely to dive into
this issue in the immediate future.

Well I guess Doug may not have used '--with-valgrind-instrumentation=2'; our
packages don't either.
Apart from that, I am also lost. Maybe we need to talk to the valgrind or
gcc maintainers?

ld-2.6.1 reminds me -- this may be a library issue. I think we just jumped
from libc6 2.4 to 2.6, and not all compilers may be aligned. Just a random
