MALLOC_CHECK_ACTION_ was already on for a travis build. I didn't add it to debug.c because of the performance
hit, but I guess if you have --enable-developer on then you don't care about performance.

Just a reminder if you're building from git and are using FreeRADIUS in performance critical situations
you must pass --disable-developer to the configure script.

There are significant numbers of extra memory checks which which will harm performance.
