Hi Simon, 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, -Stefan Simon Marlow wrote:

I'm using GHC 6.2.1 on Windows 2000.

Problem 1: -hr crashes in some circumstances.

Take this program (Test.hs):

module Main where import IO main = do readFile "large.csv" putStrLn "OK"

where large.csv is an 800K CSV file (with very small files, the bug doesn't occur). I compile with:

ghc -prof -auto-all Test.hs

and run with:

a.out +RTS -hr

I can't reproduce this bug. Just to make sure I'm doing exactly the same thing, could you send me the source code for Test.hs and "large.csv" (compressed), please?

Cheers, Simon
