Do you have a log of what the sanitizer is saying?

(There are quite a lot of sanitizer warnings on running
the main build too -- at the moment we don't have anything
in the CI that runs the sanitizers, except that patchew
does for a limited (x86-targets-only) config, to defend
the parts that we've managed to make warning-free. But
I think that the warnings I've looked at are mostly for
real-but-unimportant leaks, rather than false positives.)
