My project is broken. Very very broken. I can't even isolate the error to post here for help.

Process terminated with status 3 (0 minutes, 6 seconds)

That is the message I've been looking at for the past 8 hours. I've been outputting line numbers to my debug text file to see exactly where it was crashing, because Code::Blocks' debugger no longer works, at all.

I would change something around to make it get past the line it crashes on (there are zero compile errors so I don't know what's wrong with what's already there), and then it would crash like 5 lines after that one. I'm pretty sure my only choice is to start over from the last backup I have, unless someone else can think of some other way I can attempt to debug the failure?

Without code, it is a little difficult to help.

My guess is that it is due to a memory stump. Going beyond the bounds of an array, deleting something off the stack, uninitialised variables, double deleting, etc.

Are you building and running in Debug mode? Are you running the project with the debugger attached?

Are you using any form of source control?

yeah, when I get status 3's, It's usually due to something to do with pointers, if it's an SDL project your working on, check that all of your SDL_Surfaces are being created, initialised to NULL and are being freed properly, I swear I got a status 3 and something like that was wrong.

I don't know why, but I always hate getting status 3, I think it must be because i've gotten used to seeing it, and it normally means i've done something terrible

Nothing says "good job" like a nice clean status 0

I'll check that out next time I feel like dealing with debugging my messy code (when vacation starts)

I'm not sure what you mean by source control? Do you have an example?

Well as I've said I can't even figure out what file the error is starting in, and the whole project is somewhere around 700 lines.

Haha, that's for sure. I'll take a look at the things you mentioned.

SVN, git, CVS, Perforce.

That is small enough. Post the whole project.

Didn't you say that this happened when you rewrote string code to use character arrays? That would fit the array out-of-bounds theory...

C++ strings FTW.

Nope, I haven't rewritten any string code haha.

Alright, here ya go: http://www.freewebs.com/dandymcgee/Dand ... Broken.zip
Thanks for taking to time to look at this for me

Btw, Merry Christmas everyone!

I might have something to do with this:
You need to do this(this means Level needs a constructor)
And don't forget to delete it at the end.

Code: Select all

Level *test = new Level();

And don't forget to delete it at the end.

What should I put in the constructor? I can't get this to fix the problem.

Just leave the constructor blank for now.

I tried it with a blank constructor and it returned status 3 just the same.

I noticed :/
Me thinks it has to do with you Image::Load function that seams to be where it dies still working it.

Yeah.. but test.png exists in the images folder so I don't know why it wouldn't work? I've used that function before elsewhere I believe. Thanks for trying to help though, I really do appreciate it.

From a very quick glance:
Doesn't need to be a pointer: In int Level::Load( std::string file_map, std::string file_tilesheet ):

Always pass objects as references and const whenever possible unless there is a design reason not to. It is cheaper and faster to pass by reference then by value for non-basic datatypes and the use of const is so you don't accidently overwrite the data: tileSheet (which is currently a pointer) is not initialised or pointing to a valid memory address. Again it has no reason to be a pointer.

In short, most of your problems involve using pointers that are pointing to invalid memory.
