Vadim Yanitskiy gerrit-no-reply at lists.osmocom.orgReview at https://gerrit.osmocom.org/7265 configure.ac: add --enable-track-null option This option allows one to enable tracking the use of talloc NULL memory contexts. Useful when you want to observe not only the application root context, but also other contexts, e.g. not exposed by libosmocore. In order to obserbe all existing contexts, use: OsmoBTS# show talloc-context all ...
