Non-static plugin segmentation error

ws22

hello everybody,
i get an segmentation error if i create more than one plugin in subdirs of my project.
if i have only one subdir-project which creates the plugin everything works fine.
whats the problem?
i´m using windows xp / qt 4.8.0

thanks in advice!

I don't think anyone will be able to help without substantially more information. I don't know of anything just on the merit of creating multiple plugins in subdirs which would cause a crash.

hello mlong,
thanks for the reply!
the error occours when i emit a virtual funktion of my interface class. that happens only if i have more than one .dll in my plugins folder. if i have only one .dll plugin in it exactly this virtual funktion works perfect.
i have tried it with the plug & paint example and there i have the same error if i build a second plugin.

this is my interface:

@#ifndef HERBERTPLUGINTERFACE_H
#define HERBERTPLUGINTERFACE_H

#include <QString>
#include <QtCore>
#include <QMainWindow>

class HerbertplugInterface
{
public:
virtual ~HerbertplugInterface() {}
virtual QString echoherbertplug(const QString &messageHerbert) = 0;
};

Q_DECLARE_INTERFACE(HerbertplugInterface,"com.quins.QuinsMaster.HerbertplugInterface/1.0")

#endif // HERBERTPLUGINTERFACE_H@

and here my pro file of the plugin:

@QT += core gui sql

TEMPLATE = lib
CONFIG += plugin
INCLUDEPATH += ../Test

HEADERS +=
herbertPlugin.h

SOURCES +=
herbertPlugin.cpp

TARGET = $$qtLibraryTarget(herbertplug)
DESTDIR = ../plugins
