Dear all,
I am currently facing a problem, where gunradio segfaults, when I add a certain variable into the flowchart. I created a little apache server, to share the according code of my module, where the segfault happens (/include & /lib cpp files): http://nbws.hopto.org/ Maybe there is something wrong with the code? When I do a gdb backtrace, I get the following: [New Thread 0x7fffe0c4f700 (LWP 172481)] [Thread 0x7ffff087c700 (LWP 172476) exited] [Thread 0x7fffdbfff700 (LWP 172479) exited] [New Thread

Does anyone has an idea how to fix that? I am very thankful for every help, because I am really running out of ideas at the moment :) Best, N
