Hello,
I have a strange (low level) problem with the Data.Text library.
Running the simple program below on a certain text file causes a low level
error.
runghc ./ReadFiles.hs testfile
ghc(16402,0xb0103000) malloc: *** error for object 0x2501710: pointer being
freed was not allocated
*** set a breakpoint in malloc_error_break to debug
ghc(16402,0xb0103000) malloc: *** error for object 0x2501710: pointer being
freed was not allocated
*** set a breakpoint in malloc_error_break to debug
ReadFiles.hs: testfile: hGetContents: invalid argument (Illegal byte
sequence)
module Main where
import qualified Data.Text.IO as TI
import qualified Data.Text as T
import System
main = do
args <- getArgs
let fileName:_ = args
txt <- TI.readFile fileName
putStrLn $ show txt
Unfortunately I can 't post the specific data file.
But according to the file program it is a text file with :
Non-ISO extended-ASCII text, with very long lines, with CRLF, LF line
terminators encoding.
How can I debug this problem ? What would you guys do ? Trying gdb ?
thanks in advance,
Pieter
