Subject: at_exit in C extension

Hello,

For ruby 1.8 i used registering at_exit in C via eval (quite hackish i know) 
as in:

void Init_Mymodule()
{
	...
	module = rb_define_module("Mymodule");
	rb_define_module_function(module,"myfunc", ...
	...
	rb_eval_string("at_exit do Mymodule.myfunc end");
}

but that doesn't work with 1.9/head anymore (crash). However when i move the 
at_exit call to the ruby script which uses the extension, it works just fine. 
So, what is the correct way of using at_exit for C extension function ?

Thanks,
Jan
