I think using SANITIZE=memory would catch these, but it needs some
suppressions tuning. The weird "zlib reads uninitialized memory" error
is a problem (valgrind sees this, too, but we have suppressions).

What version of zlib do you use?  I've heard some good things about
v1.2.11 improving matters, though I haven't checked yet.

1.2.8.dfsg-5, from Debian unstable. I'm happy to try v1.2.11 once it
hits unstable or experimental. :)
