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
