[examples] models_animation sig fault

[chriscamacho]

when compiled from cmake makefiles it just seg faults without running, however running from a real Makefiles it does run showing just a bunch of animated red boxes and segs on exit

is the invalid pointer because something couldn't be loaded ? - suggestion have your own version of free that zero's pointers on free and doesn't free null pointers.... (but does log attempt)
You get a less useful and short backtrace if the animation isn't run before quit.
