tt may be that GHC 7.8 optimizes the program better.
Compile with -O0 and see if it runs out of memory, too.
If so, you can just optimize the program by hand.
I'd suggest making a heap profilie with -O0 or in GHC 7.6
and finding out where the memory goes.
Of course, it's possible you've hit a compiler bug,
but it makes sense not to start with that assumption.
Have fun,

I have a program I submitted for a Kattis problem: https://open.kattis.com/problems/digicomp2 But I got memory limit exceeded. I downloaded the test data and ran the program on my own computer without problems. Eventually I found out that when compiling with GHC 7.6.3 (the version Kattis uses) rather than 7.8.3, this program runs out of memory. Can someone explain why it only works on the later compiler? Is there a workaround so that I can submit to Kattis?
Thanks, David
