[BUG] rb_gc_mark(): unknown data type 0x34(0x8a69570) non object

I get the following error:

perm.rb:17: [BUG] rb_gc_mark(): unknown data type 0x34(0x8a69570) non object

In rb_callcc(), th->thread is assigned too late (and not set to zero in
THREAD_ALLOC())

If ruby call the GC when it's in scope_dup() it will give the error
`unknown data type' when it try to mark th->thread
