Hi all,

It's a tad tricky to do run-tests -m on my system, as every PHP call leaks:

Anyone have experience with this and advice on what I need to upgrade?

It's normal.  Create a suppression file and ignore those.

eg.

--gen-suppressions=yes

And it isn't PHP calls leaking.  It's just the way libdl does stuff.
