Hi Michele,
if you built GNU Radio/gqrx with gcc, then the GNU Debugger might be of
immensive help.
First make sure you've built GNU Radio with debugging symbols ("cmake
-DCMAKE_BUILD_TYPE=RelWithDebInfo [...]"), then start gqrx in the debugger:
?> gdb $(which gqrx)
[lots of text from gdb]
(gdb) run [<enter>]
should start gqrx and run until it segfaults. then use the backtrace
command in gdb:
(gdb) bt [<enter>]
which should show you in which function call hierarchy the fault occurred.
Greetings,
Marcus
PS: don't worry about your English, it's quite fine :)
