I've tried your code with ghc-6.6.1 under x86 linux with binary-0.3: http://hackage.haskell.org/cgi-bin/hackage-scripts/package/binary-0.3
It does terminate for me with and without profiling and/or optimization, when I pass in the source file itself as input:
$ ./foo < foo.hs
Is this a confirmation of your observation or am I (are we) doing something wrong?
I don't know what's supposed to happen if you pass it invalid input (such as the source file); for me it it seems to just eat up all available memory. However, I observed the stack overflow when actually passing in *valid* input,that is a tuple of two IntMaps previously serialized using Binary. If that helps I copied the input file I used here: http://computing.dcu.ie/~gchrupala/okok I'm running ghc-6.6.1 on linux fedora 6 on x86, binary-0.3 Best, -- Grzegorz
