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.
