The unmodified distributed 5.3 all-in-work apparently ALWAYS eventually crashes onstartup after trying to load a dylib and then staving, if I do it enough times, but thus far the ones I built do not do this.<br class=""></blockquote><div class=""><br class=""></div><div class="">If you run with an assert 5.3 VM build do you see anything indicative?
