You can start ghci with the -K option to increase the stack size --
ghci +RTS -K256m -RTS
for example, sets the maximum stack size to 256 MB. However, stack
overflows are usually (though not always) a sign of buggy code, as
they're often caused by infinite recursion, and you want to be
notified of that sooner rather than later.
