--- Comment #27 from John Kanapes <jkanapes at yahoo dot com> --- Hi, I have uploaded my sources to https://www.dropbox.com/s/ao4l5h62h3paujq/test.tgz?dl=0 It is a tar.gzip archive. Expands to a test directory with flat files (10) and 1 Makefile. Main executable is capture. In Ubuntu 20.04 you will also need to install: sudo apt-get install flex sudo apt-get install libuhd3.15 sudo apt-get install libuhd-dev uhd is the ettus driver for their usrp radio. You don't need the radio for the test. Makefile provides 3 targets: (exec), db, clean exec: make without arguments will build capture with -O3 to test bug db: builds capture with gdb flags and without any optimizations clean: cleans all intermediate files and executables Problem reproduction: capture -h Expected response: SIGILL core if built with (exec) Syntax and arguments if built with debug Plz let me know when you have downloaded it, so that I can block the shared link. I can help with all installation and problem reproduction. I will appreciate it, if you can reduce the code before publishing it to a smaller part that can trigger the problem. Gl John
