Category: hslibs/text Group: 6.0.1 Status: Closed Resolution: Fixed Priority: 5 Submitted By: Remi Turk (remit) Assigned to: Simon Marlow (simonmar) Summary: SIGSEGV in Text.Regex Initial Comment: Hi all, while writing a little download-some-weblog-program I encountered what appears to be a memory management bug in Text.Regex of ghc-6.0.1. Both 6.0 and 6.0.1 crash. I didn't try other versions yet. possible interesting information can be found at: http://home.wanadoo.nl/remi.turk/tmp/LJGet/core.bz2 http://home.wanadoo.nl/remi.turk/tmp/LJGet/grepHref.bz2 http://home.wanadoo.nl/remi.turk/tmp/LJGet/grepHref.hs If I need to provide additional information or isolate the problem into a smaller code-fragment, please let me know. Happy hacking, Remi some gdb-info: {- gdb copyright info... -} Program terminated with signal 11, Segmentation fault. {- reading symbols from... -} #0 chunk_free (ar_ptr=0x0, p=0x4045cbf8) at malloc.c:3049 3049 malloc.c: No such file or directory.

I've just fixed it in the HEAD, but I'm afraid there isn't a workaround for 6.0.1. Text.Regex is sadly broken, *sigh*. The URLs in the bug report were unreadable from here because our proxy is blocking that site, for some unknown reason. ---------------------------------------------------------------------- Comment By: Remi Turk (remit) Date: 2003-09-09 23:36 Message: Logged In: YES user_id=26642 *verifying* yes it does crash with 6.0.1. I can reach the files without any problem, both from home and from university. Are they still unreachable? ---------------------------------------------------------------------- Comment By: Hampus Ram (hampusr) Date: 2003-09-09 21:47 Message: Logged In: YES user_id=159064 I too get a sigsegv when I run the given code (the links work just fine for me) and I've tried with both ghc 6.0.1 and CVS version from about a week ago. ---------------------------------------------------------------------- Comment By: Simon Marlow (simonmar) Date: 2003-09-09 10:58 Message: Logged In: YES user_id=48280 Strange - I thought I fixed this bug between 6.0 and 6.0.1. You're absolutely certain it happens with 6.0.1? The URLs in your bug report don't work. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=108032&aid=802692&group_id=8032 _______________________________________________ Glasgow-haskell-bugs mailing list [EMAIL PROTECTED] http://www.haskell.org/mailman/listinfo/glasgow-haskell-bugs
