I can reproduce this with OpenOffice. Here's the backtrace:
Debugger entered--Lisp error: (error "Stack overflow in regexp matcher")
looking-at("\\([ ]*\n\\)*[ ]*#\\+TBLFM: *\\(.*\\)")
org-table-get-stored-formulas()
org-table-get-formula(#("1" 0 1 (face org-formula fontified t)) nil)
org-table-eval-formula(nil #("1" 0 1 (face org-formula fontified t)))
org-table-maybe-eval-formula()
org-ctrl-c-ctrl-c(nil)
call-interactively(org-ctrl-c-ctrl-c nil nil)
Best,
Matt
