Hi again. I'm having issues closing my server program. It's causing a segfault in the GC with the following backtrace:

Win7 x64 (but compiled with -m32), compiled with asserts, debug info, and gdb jit stuff.

First, is this something I did, or a bug in the VM? Second, if the former, what did I do wrong, and/or how can I track the issue down?
