    At work I am using a Siemens-Nixdorf keyboard for many years now.

    To give your fingers some relief/training I can recommend a rubber ring.

      That keyboard looks beautiful! Does it have mechanical keys?

        That’s not a very good bug report. Where’s the gdb backtrace?

          Could you provide a backtrace? It’s hard to try to guess what’s wrong without any context.

          I’ve had a bug report today, and it’s been found that such log lines crash the program (the cause is known and the issue will be fixed soon) :

          1.2.3.4 - - [18/Nov/2013:19:54:25 +0100] “-” 400 0 “-” “-”

            I thought the snippet in my comment had a little beauty of its own, therefore no backtrace.

              I believe this is the same bug occurrence of the bug which has been reported and is now fixed.

              Logswan 1.01 has been tagged. Could you test and report if it solves your issue? Thanks.

            Wonder if Valgrind would’ve caught this? Also wondering how fast I could get an equivalent in Haskell to go. We have a HyperLogLog library that I’ve been waiting for an excuse to use outside of work.

              There’s no way to tell if valgrind would have helped unless @allan provides a stack trace or example input that crashes logswan.

              My best guess? Stuff like this would be more probably caught by afl fuzzing since I know fcambus uses logswan regularly on real life data. Though again, without the input log file or a stack trace there is no way to tell.
