Hello, Why would ghci run out of heap space (and crash) the second time I run a computation? More specifically, I have a ghci session which goes something like this: *Analysis>run [ ... print out of a very long list ...] *Analysis>run [ ... partial print out GHC's heap exhausted: current limit is 268435456 bytes; Use the `-M<size>' option to increase the total heap size. Shouldn't the garbage collector free up everything in between my top-level function executions? Also, there doesn't appear to be a '-M<size>' flag for ghc (I'm using 6.4.2 on windows xp). thanks, Jeff -- This e-mail may contain confidential and/or privileged information.

I'm sure there is. You must add following arguments: +RTS -M<size> -RTS Note the rts magic. Regards, -- Intelligence is like a river: the deeper it is, the less noise it makes
ghci keeps the value of your last computation in a special variable
called "it". Therefore, the value of your last run can't be garbage
collected until the current run is finished. Try "print run" or type
in a dummy expression in between runs.
