Thanks. I have also tested that a fresh rebuild of 2.5.1 does not exhibit
the problem, so it is not caused by updated build-deps.

Upstream recommends to disable assertions in production builds, see

https://trac.pjsip.org/repos/wiki/FAQ#assert

When I do this I get a full-blown segfault (and we lose a symbol, so
although we only have one rdep it would technically involve a library
transition). I've reported the segfault to the upstream mailinglist

I will try the latest SVN snapshot later.
