Re^3: How do you find keys of a Blessed Hash?by Corion (Pope)

... most of my code is tied in with library functions and problems I find are never in simple 1 liners, but buried amongst 2000 other lines of code. Trying to reproduce it in a short example invariably removes the ability to reproduce the bug.
That is the point of debugging your code. By reducing your code to a small snippet, you stepwise eliminate all unrelated parts. And usually, if the symptom goes away between two editions of your program, it is highly likely that the part you changed last is related to the symptom. So the trick is to keep removing parts without changing the symptom until only the core code related to the symptom is left over or until it becomes clear to you what the cause was.
If this sounds like work, that is because it is. This is why you need to do the work of removing all the unrelated cruft from your code, instead of feeling entitled that others wade through your code.
No. All I've seen from you were programs that could not run on their own because they relied on various other libraries. You demonstrated enough lack of grasp on your environment that it is highly likely that you mixed up compiler versions and Perl versions. Doing so is advised against and will lead to core dumps. Claiming that you have "clearly demonstrated" when you just tell vague tales of an environment that you yourself messed up is misleading.
I'm more than happy to share code... AND have done so in the past. But I didn't sufficiently deconstruct my program into an artificial and thereby, unrelated test case and got chastised for it by 'you'...#985099.
I think you shouldn't feel "chastised". I mean Re^6: Why isn't a fatal error trappable? as solid advice from experience. Debugging a program is not like retelling an epic tale from memory where the minutiae don't matter. Debugging is assiduously going over the program and its output with a fine comb, for as long as it takes. We don't know about your environment and your library versions etc., but for debugging, reproducing your environment is necessary. If you make it difficult for us to reproduce your situation, you are making it difficult for yourself to get help.
I know it's demanding of me, but your tone was spiteful and you even got several votes indicating your spiteful tone to put me down was appreciated. That doesn't come off as a very friendly helping community IMO...but I know my opinion doesn't count for much.
Seriously, I'm not doing this to be "unfriendly". I'm doing this to get results, to get programs debugged. And the only way I know to debug programs together with other people is to enable people to reproduce the situation. I give you that advice to enable others to help you. If this comes across as "unfriendly" to you, and if you feel that you need more hand-holding, then "listening" to the feedback is not enough. You will have to start doing work yourself, as has been outlined several times already - by reducing your problem to a small, self-contained program that exhibits the problem.
