How to use qwt6.0.2 with visual studio 2008 in debug mode.

Hi,
I had installed qt4.8.4 and qt plugin for visual studio to build qt4 project within visual studio 2008. I also had compiled the qwt6.0.2 in debug and release mode manually with instruction in the INSTALL file. Now, I could build and run the qwt examples in release mode. When I try to debug these examples, the application could not be launched.
The following is the output:

The program '[5608] simpleplot.exe: Native' has exited with code 1 (0x1).

I had debug into the application and found that the application exit when I tried to construct an instance of QwtPlot class. Could anybody give me some advice on how to deal with this situations or recommend to me the version of an stable combination of qt and qwt for visual studio or mingw.
