This is because most programs with threads have less stack space per thread than a program with no threading support.

Formatting means that the symbol fun in the second line signals by layout that the construct in the first line is finished. What are the disadvantages of a delta wing biplane design? So generally you have to give new names to values you obtain as the result of a 'modification'. p) lines :: String -> [String] lines "" = [] lines s = let (l,s') = break ('\n'==) s in l : case s' of [] -> [] (_:s'') -> lines

  2. Say you have a function: sum = go 0 where go accum [] = accum go accum (x:xs) = go (accum+x) xs Which, incidentally, is the same as sum = foldl

  5. In Windows, a stack overflow error can be caused by certain types of malware.
  6. For example, if a recursion never terminates, it will eventually hit the stack limit and "overflow." Even if a recursion is terminating, it may overflow if there are simply too many

But not (in general) let x = foo x, that loops. –Daniel Fischer Jan 4 '12 at 15:03 2 And such shadowing is highly discouraged. This is a type error(!): concat expects a list of lists, but is instead passed a list of numbers.

Partial Application Bug4Hugs `/` vs. This is always possible, because the class of primitive recursive functions is equivalent to the class of LOOP computable functions. This never gives an answer, but rather goes on forever; after some time it overruns the `control stack' which causes the message that you saw.

To avoid this in cases where strictness is desirable, you can use foldl' foldl' f x (y:ys) = (foldl' f $! I use WinHugs. cont where cont [email protected](c:_) | p c = "\\&" ++ s cont s = s -- Unsigned readers for various bases readDec, readOct, readHex :: Integral a => ReadS a readDec

For example, foldl f x (y:ys) = foldl f (f x y) ys In contrast, foldr is not tail recursive foldr f x (y:ys) = f y (foldr f x ys)

The program is a correct program, in which x is applied to the function div, hence the error appears as a mis-typing. This modified tail recursion pattern is encapsulated in Data.List.foldl', so: sum = foldl' (+) 0 A good rule of thumb is to never use foldl, because it always builds up giant showChar ')' else p showField :: Show a => String -> a -> ShowS showField m v = showString m . Not the answer you're looking for?

Stack overflows are made worse by anything that reduces the effective stack size of a given program.
