I am investigating a similar problem with Kross + QtRuby. 

I have replaced in VirtualMethodCall::callMethod() , the rb_funcall2 with a 
rb_rescue2 to catch the exception (I can give you a patch if you want, but 
it's pretty messed up with a lot of debug call). And the exception I get 
is "SystemStackError: stack level too deep".

So I am currently try to track the error inside ruby VM, and as far as I can 
see, at some point the length of the stack become negative, which seems to 
confirm some sort of random memory corruption.
