VLC-Qt _CrtlsValidHeapPointer(pUserData) error

Question

I want to add VLC-Qt to my application and currently I am struggling with following error:

I am using VLC-Qt_1.0.1_win32_msvc2013.7z from here and building my application with MSVC 2013 32bit, so I have no idea and couldn't find anything else which resolves my issue.

Has this happened to anyone?

EDIT code: Only code I am trying to execute is

_instance = new VlcInstance(VlcCommon::args());

EDIT2: This is the only thing I get from app output before it crash:

VLC-Qt "1.0.1" initialised
Using libvlc version: "2.2.2 Weatherwax"

SOLUTION: Issue here is that precompiled library downloaded from here was build in Release mode where I've building my application as Debug.

Press retry and look at the call stack to find the place in your code where the error is happening. Perhaps you're trying to free/delete a pointer that wasn't allocated with new/malloc. — Retired Ninja, Jul 26 '16 at 20:42
I have and sometimes the app crash and sometimes it opens me some Qt related code (like header file of QList but I am not using QList...) — carobnodrvo, Jul 26 '16 at 20:46

I just want to add official solution here.

So the problem was that I was using Release dlls while building Debug mode. You can switch build mode (bottom left corned) to Release or more general solution: edit your *.pro file:

Debug:LIBS       += -L.../vlc-qt/lib -lVLCQtCored -lVLCQtWidgetsd
Release:LIBS       += -L.../vlc-qt/lib -lVLCQtCore -lVLCQtWidgets
INCLUDEPATH += ../vlc-qt/include
