Two problems with heap profiling
doc at drjava.de
Sun May 9 17:36:16 EDT 2004
I found a suitable large file that is certainly on your harddisk - the
GHC 6.2.1 user's guide (users_guide.ps, 1205288 bytes) :-)
I attached new Haskell source file (you will need to adapt the file
path). Compilation and invocation as in my previous mail. The program
crashes every time I run it (Windows XP this time, but I assume that
doesn't make a difference).
Thanks in advance for your help,

-------------- next part --------------
module Main where
main = do
contents <- readFile "/ghc/ghc-6.2.1/doc/users_guide.ps"
putStrLn $ "lines: " ++ show (length (lines contents))
