It's an old issue that we never figured out - it has to do with the way R signals errors. For some reasons the sigjmp caused by an error will destroy the stack in recent GUI versions. Unfortunately it's not something the GUI caused per se (AFAIK) but rather something that changed as a side effect of something entirely unrelated (maybe compiler versions?). The real reason is so far unknown. I'll see if I can dig deeper ...

Cheers,
Simon
