Sorry for the delay in coming back to you regarding this notification.
You can consider this as a false alarm, caused by the fact that the
above configurations use QEMU, which is not (currently) compatible
with LSAN (which is enabled by ASAN).

We are working on a fix in our testing framework to avoid such issues
in the future.

Thanks,

Christophe
