I have downloaded the latest pre-release for v5.3 (plt-5.2.901.1-bin-i386-win32.exe). All of my PLaneT collections load and run fine. But, my large application at work fails to run - it dies during startup with "Seg Fault (internal error during gc) at 58720044" printed (twice) in a new window. It's running under Windows XP. I've attached a screen shot of the Visual Studio debugger error window with slightly more information. Let me know if there is anything else I can provide.
