I would try -c first (turn on the compacting collector). Adding more generations (eg. -G3) might help, and setting a maximum heap size (eg. -M512m) will cause GHC to try to trim down its memory use when it gets close to this boundary.
Unfortunately neither of that helped. It appears that ghc simply _needs_ that amount of memory. No matter what option I gave, at one point it hit the 800 MB limit and aborted. (I specified -M800 because if it used more memory than that, the machine stood basically still with thrashing.) Looks like I'll have to support the memor chip industry ... The problem is that if a 512MB machine cannot compile it, I wonder how the _users_ of my program will get along. I guess they'll tend to have smaller machines than the average software developer does. -peter
