Please note that this message will contain a full copy of the comment thread, including the initial issue submission, for this request, not just the latest update. Category: Profiling Group: 6.4 Status: Open Resolution: None Priority: 5 Submitted By: Nobody/Anonymous (nobody) Assigned to: Nobody/Anonymous (nobody) Summary: segmentation fault when profiling large case Initial Comment: If the attached file is compiled with -prof -auto-all, the binary produced will segfault (even if RTS profiling options are not present). This seems to be caused by a combination of a case statement with a large number of branches and a relatively complex value at the end of each branch - reducing the number of branches by one or changing any of the data declarations to newtypes eliminates the segfault. ---------------------------------------------------------------------- Comment By: Fergus Henderson (fergus) Date: 2005-09-14 11:10 Message: Logged In: YES user_id=135331 No, I am not the original submitter. ---------------------------------------------------------------------- Comment By: Simon Marlow (simonmar) Date: 2005-09-13 01:51 Message: Logged In: YES user_id=48280 Fergus - are you the original submitter? What was different about the environment in which the bug exhibits? ---------------------------------------------------------------------- Comment By: Fergus Henderson (fergus) Date: 2005-09-05 14:48 Message: Logged In: YES user_id=135331 I tried reproducing this using ghc 6.4 on Debian Linux, but I was unable to reproduce the bug. The program compiled fine with "ghc -prof -auto-all bug.hs" and I was able to get a profile by running "./a.out +RTS -p" and looking at a.out.prof. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=108032&aid=1277825&group_id=8032 _______________________________________________ Glasgow-haskell-bugs mailing list [email protected] http://www.haskell.org/mailman/listinfo/glasgow-haskell-bugs
