in thread How to find perl line after segfault.

Sorry, but I never had any luck at all with open3() when I first tried it, as a consequence I never use it. You'll need help from someone who does.

As an aside; I wasn't aware that open3(), accepted strings for the file handles. Nor does anything in the documentation lead me to believe it does.

    Ok, maybe that's it.

    Actually, I notice now that CallTrace outputs to STDERR not STDOUT, so it wouldn't work for that reason either.

    Thanks for your help.

      As you're sending the output to a file, why not just?:

      system q[perl -d:CallTrace i-Mage.pl 2> trace.txt];

        Well I shall probably have to do that, But then when it segfaults I wont be able to manage the crash, It'll just be a case of restarting the application. I suppose since I have a crash file (the trace.txt), I can look for trace.txt files at the startup of a programme and then do whatever I need to.

        Regards

        Steve.
