Hi,
I just tested with gnuradio-3.7.1 on gentoo and the example worked for me.
Some days ago I had a lot of segfaults, too. I recompiled pyqwt and qwt5
and the segfaults where gone.

Hi
I have compiled gnuradio severel times from git source with different
compile options on debian stable.
But if i run gnuradio with the following i always get a segfault, and i
dont know why :(
Maybe someone can help me.
Regards Dominik
