I don't have access to a windows 7 machine to test this, nor do I have any knowledge of windows 7 debugging.

I've looked back over your original backtrace. Assuming your still seeing the same issue (gc_sweep(), unknown data), I'm guessing that my patch is not the core cause of the issue, but is rather just running some code path that causes a GC bug.

If this is the case, then the GC bug exists already and needs to be fixed whether or not my patch is applied.

If this is considered a show stopper for 1.9.2, then it's the GC bug that is a show stopper, not my patch. Not applying my patch because of the GC bug solves nothing, but the GC bug will still exist and users will hit it some other way.

I currently do not have the knowledge to track down the GC bug, but I hope that someone on ruby-core does and can assist.
