Bingie!

There's a data structure used to pass language translation data back to 
the offending program from another that loads it from a user space. It 
seems that in the offending program, the receiving structure hadn't been 
updated to reflect the latest expansion of the translation data. And 
unfortunately, the INFDS pointer was evidently in the overflow zone.
