problems with qwt-5.0.2 and label scale draw

Good morning.

I noticed that my program, that uses qwt-5.0.2 core dumps in the 
QwtScaleDraw::alignment () method of the library.

Is there any issue related to it, as far as you know, possibly solved 
in qwt 5.1?

Thank you very much for your attention.

Follows the backtrace of the program, from the core dump.

Core was generated by `./blmprofile'.
Program terminated with signal 11, Segmentation fault.
