Hello everyone. I'm new, so hi 
I am currently having an issue with my Heap corrupting. And after a couple hours of pulling my hair out, Application Verifier gives the following output:

The line allegro-5.0.10-monolith-md!al_cond_timedwait+eb ( @ 0) catches my eye. The program crashes on al_wait_for_event(event_queue, &ev); everytime (Visual Studio 2015 breaks at a breakpoint on that line everytime I run my program).
So what do you make of this? I'm kinda at a loss.
Thanks.

memory corruption is usually a PEBKAC error, and is not always obvious where the problem is coming from.
Under linux i like to use valgrind to figure out where the error is comming from. I don't know of any equivalent on windows unfortunately.

Hello,
An alternative for valgrind on Windows is Dr. Memory. It comes up with these results:

Can you make something of this?
If you need more details / code, please ask.
Thomas Fjellstrom
Is there another mode that shows more than just leaks? valgrind also shows improper memory access (reads and writes), which is what we really need to see.

But I don't think those uninitialized reads are the problem, because this problem still occures when I completely comment out the loop (except for the al_wait_for_event(event_queue, &ev) ofcourse). And every uninitialized read it reports occures in the loop.
Is this more useful?
Thomas Fjellstrom
You may need to show some code. Uninitialized accesses are a sign you're doing something wrong. ALWAYS initialize your variables.

Well, here is LuaScript::Execute for example:
1bool LuaScript::Execute()
2{
3 if (luaL_loadfile(LuaState, resource.c_str()))
4 {
5Line 80 -> std::cout << "Lua script " << resource << ": file not found." << std::endl;
6 return false;
7 }
8
9 if (lua_pcall(LuaState, 0, 0, 0))
10 {
11 LuaHelpers::StackDump(LuaState);
12 al_show_native_message_box(display->Get(), "Error", "Script failure", Stack::Get<string>(LuaState, Stack::Top).c_str(), nullptr, ALLEGRO_MESSAGEBOX_ERROR);
13 }
14
15 std::cout << "Lua -> Script " << resource << " loaded\n" << std::endl;
16
17 return true;
18}
Resource is an std::string, and if it was empty c_str() would zero-terminate it.
And FontManager::LoadFromList:
1void FontManager::LoadFromList(string list)
2{
3 string location = "resources/lists/" + list + ".txt";
4
5 auto lines = Filereader::ReadAndSplit(location, "|");
6
7 for (vector<string> &line : lines)
8 {
9 fontNames[line[0]] = line[1];
10 }
11
12Line 21 -> std::cout << "Font list loaded: " << list << "\nFonts loaded: " << lines.size() << "\n" << std::endl;
13}
Same story. Also, these functions have worked perfectly for a good while, and they haven't changed. That makes me believe that it does not cause the error.
And this is Game::Initialize:
1void Game::Initialize()
2{
3 auto texScript = ScriptContainer->Insert("textures", new LuaScript("scripts/textures.lua"));
4 texScript->RegisterFunctions(TextureManager::LuaTextureFunctions);
5 texScript->Execute();
6
7 MenuSystem->CreateMenus();
8 GameWorld->Create(MAP_WIDTH, MAP_HEIGHT);
9}
This executes a Lua script in which textures names and locations are defined.
I have already checked for things like Lua stackoverflows, but that doesn't seem the be the issue either.
I'm using Allegro 5.0.10 with Windows 10 by the way (sorry for not mentioning that before).

Well... now that I remember, once I had a heap corruption error that only happened on Linux but not on Windows. What was more interesting with this error was that I could only reliably replicate it when the screen mode was any of the automatic full screen modes (full screen windowed not included).
Unfortunately lost access to the machine in which the error happened and was never able to pinpoint the exact cause for this strange situation...

It's possible your event_queue isn't valid or was corrupted.
Otherwise I really can't see any real error in what you're showing (but I didn't study your posted code in depth).
If it can be built on linux, I can take a look at it and see if i can find the issue.

I ended up redownloading allegro, recompiling lua, and changing things around in main(). I don't know what did it in the end, but it works know. Weird stuff.
In any case, thanks a lot for helping! I really appreciate it 
Thomas Fjellstrom
It could be a compiler version mismatch or some other thing. Or its still got memory corruption and your reordering of stuff is hiding it 
Memory corruption is like that. You can change one little thing and hide it, or show a problem you had for ages that just didn't cause a crash before.

Sounds like an uninitialized pointer use or a bad malloc to me.
