in thread How can I free the memory of a XML::Simple-Object

I have found that for CVs/subs Devel::Size will count entire package/class (GVs and every slice in the GV and all the shared key names of the stash and all sub stashes) that a CV is in for the size of a single sub. An XSUB with no optree comes in at a dozen KB. Be careful of what Devel::Size tells you.

    Indeed. For tracking absolute sizes, that can be a problem.

    But for the purposes of tracing leaks, whether they are optimistic or pessimistic for any particular construct, so long as the measurements are consistent, then the purpose is well served.


    With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'
    Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
    "Science is about questioning the status quo. Questioning authority".
    In the absence of evidence, opinion is indistinguishable from prejudice.

    RIP Neil Armstrong

[Marshall]: stevieb wish you well with water problems, my water was off all day Monday for repairs. Any more progress on .exe info problem?.
[stevieb]: Marshall: no. I commented on the thread yesterday. Visual Studio updates the tags ok, but corrupts the exe
[stevieb]: I advised the OP that a possible workaround would be to add a version function/flag that displays the required copyright/license info instead
[Marshall]: Darn! I'll look at the thread. Must not be updatinga byte count somewhere. The .exe format is a complex critter.
[stevieb]: that way, it's still "hard coded" into the exe at least, despite not being visible via Properties
[Marshall]: I also looked into PerlApp from Active State, but they don't sell their Dev Kit independent of a very expensive ($1,200) per year license anymore.
[Corion]: I would assume that the PE format hasn't changed that much since the days of yore, but it seems that I would be wrong in that assumption
[Marshall]: When I bought my copy 15+ years ago, it was just a couple hundred bucks.
