I expected that it might run out of memory. What did surprise me was the
*stack* overflow. I do not use recursion in my program except for a

1) What precisely is a thunk?
It's a memory cell that says 'I'm an unevaluated value, to evaluate me
do X'. For example, consider the differences between the following
programs:
(common for all that follows)
myFunc :: [Int] - [Int]

3) I tried using +RTS -Ksize as suggested, but these options do not
seem to be passed through if I use --make. How can I use both, these
compilation flags and --make?
They aren't compile options; they're runtime options. The GHC

Did you compile with -O (optimisations). Sometimes this fixes
Hi
Did you compile with -O (optimisations). Sometimes this fixes things,
and its just good practice.
It's slower to compile, and might fix things in GHC Haskell, but other
compilers don't all have -O flags, so its generally best to make your
program at least have the right sort of time/space
