[Haskell-cafe] what is a stack overflow?

[S. Alexander Jacobson]

Thank you iavor.  But the -K option doesn't appear 
to work with ghci.  And I guess the bigger 
question is what sort of code  causes a 
stack overflow.  If 5M is enough stack for most 
programs then I obviously have some basic coding 
error which is causing a stack overflow...

What sort of code causes that?
