I have now reduced this crash to a single line in the project file:

Qt Code: 
  1. QT -= gui

With this line, the crash occurs. Without this line, is does not... weird.

For some reason, qmake implicitly builds against QtGui, even though there is no obvious gui dependency in my code or qtservice. I really don't want my binary to depend on the gui libs, so i supress it using the line above...

Code:
Qt Code: 
  1. #include <QCoreApplication>
  2.  
  3. #include "../qt-solutions/qtservice/src/qtservice.h"
  4.  
  5. class Service : public QtService<QCoreApplication>
  6. {
  7. public:
  8.   Service(int argc, char** argv, const QString& name)
  9.     : QtService<QCoreApplication>(argc, argv, name)
  10.   {
  11.   }
  12.  
  13. protected:
  14.   void start()
  15.   {
  16.     logMessage("Start");
  17.   }
  18.  
  19.   void stop()
  20.   {
  21.     logMessage("Stop");
  22.   }
  23. };
  24.  
  25. int main(int argc, char** argv)
  26. {
  27.   Service service(argc, argv, "Test service");
  28.   return service.exec();
  29. }
