Thanks for trying that. I've largely switched to ASan over valgrind
because it runs _so_ much faster. Unfortunately it seems to miss
these uninitialized-memory cases.

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).
