An empty project with libkexiv2

My application crashs when I try to use libkexiv2.

It crashs with the Mageia rpms of Exiv2 (0.23) / KExiv2 (0.23) and also with a manual build of Exiv2 (0.24) and the latest version of libKExiv2.

I created an empty QtCreator project (Qt5.4), with an empty main file (just with "QCoreApplication a(argc, argv);return a.exec();").

When I run my project with this option into the .pro file:
LIBS += -lkexiv2
LIBS += -L/home/thierry/Développement/libKExiv2/libkexiv2/lib
the software crash with this message:
*** Error in `/home/thierry/Développement/BUILDS/build-Test-Desktop_Qt_5_4_0_GCC_64bit-Debug/Test': realloc(): invalid pointer: 0x00007fc5fb39c0e0 ***

If I remove this option, all works fine.
It run also with the Exiv2 library.

Is it a bug of libkexiv2?

It crash in Qt5.

Libkexiv2 that you use is KDE4/Qt4 version based, so uncompatible

You must use libkexiv2 ported to Qt5. Look here for details :

Not reproducible with digiKam 7.3.0 and Exiv2 0.27.4
