Assert error when using id3lib

Leodido

Hello guys,

I'm trying to code a little application that reads some mp3 files then decode the id3tag using id3lib and display everything a in table view.

I'm currently trying to make the id3lib working but I'm having a very weird assert error when iterating on the id3 frames.

Here is the assert I'm getting.

Microsoft Visual C++ Debug Library

Debug Assertion Failed!

Program: ...sktop_Qt_5_0_1_MSVC2010_32bit-Debug\debug\MusicLibManager.exe
File: f:\dd\vctools\crt_bld\self_x86\crt\src\dbgheap.c
Line: 1424

Expression: _pFirstBlock == pHead

For information on how your program can cause an assertion
failure, see the Visual C++ documentation on asserts.

(Press Retry to debug the application)

Abort Retry Ignore

And the code that produces it, which is just a copy/paste from an example on the id3lib page.

@// Lists all the ID3Frames
QStringList mp3Tag::listID3Frames(void)
{
QStringList frameList;

if (this->isMp3Loaded())
{
    // use an std::auto_ptr here to handle object cleanup automatically
    ID3_Tag::Iterator* iter = mp3FileTag.CreateIterator();
    ID3_Frame* myFrame = NULL;
    while (NULL != (myFrame = iter->GetNext()))
    {
        frameList << myFrame->GetTextID();
    }
    delete iter;
    qDebug() <&lt; frameList;
}

return frameList;

}@

This is how I added the id3lib to my project

@win32:CONFIG(release, debug|release): LIBS += -L$$PWD/../libs/id3lib-3.8.3binaries_win/release/ -lid3lib
else:win32:CONFIG(debug, debug|release): LIBS += -L$$PWD/../libs/id3lib-3.8.3binaries_win/debug/ -lid3lib
else:unix: LIBS += -L$$PWD/../libs/id3lib-3.8.3binaries_win/ -lid3lib

INCLUDEPATH += $$PWD/../libs/id3lib-3.8.3/include
DEPENDPATH += $$PWD/../libs/id3lib-3.8.3/include

win32:CONFIG(release, debug|release): PRE_TARGETDEPS += $$PWD/../libs/id3lib-3.8.3binaries_win/release/id3lib.lib
else:win32:CONFIG(debug, debug|release): PRE_TARGETDEPS += $$PWD/../libs/id3lib-3.8.3binaries_win/debug/id3lib.lib
else:unix: PRE_TARGETDEPS += $$PWD/../libs/id3lib-3.8.3binaries_win/libid3lib.a@

I'm very new to Qt so maybe I did something wrong?
Could anyone give me an hand?
The assert happens on the frameList << myFrame->GetTextID(); line

based on some googling it seems that you need to rebuild all the libs involved, qt as well as libId3tag. Still a guess.
