 No, this is not the solution. If you make a right use of Data_Make_Struct
 ptr->data2 == NULL before the call to Data_Make_Struct() and you can test
 this in the mark functions.

 Don't say this : this is *stupid*

 First learn how to use the ruby API, and remove *your* bugs in the source
 of your extension before trying to say such stupidities.
