Description
program crash at start up
#include <QApplication> #include "connectiontab.h" #include "global.h" int main(int argc, char *argv[]) { QApplication app(argc, argv); ConnectionTab *conn; conn = new ConnectionTab; conn->show(); return app.exec(); }
only happens when linked with an external library; removing the conn* lines above removes the problem!
debug log follows:

The program used to work, with older linux, gcc, icu and qt
similar problem with qt5 However all my kde apps are ok.
