X-Git-Url: https://git.mxchange.org/?a=commitdiff_plain;h=6ed0ece57ce8a8db84c462a4a147b5e061043564;p=flightgear.git

While I had the valgrind rig set up, I took the opportunity to plug a
bunch of memory leaks that had accumulated over the years.  FlightGear
doesn't currently bother to destroy and recreate a YASim context, but
at least it can do so now without worry.
