https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D238840 Bug ID: 238840 Summary: 'top' segmentation fault on terminal resize Product: Base System Version: 12.0-RELEASE Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: bin Assignee: bugs@FreeBSD.org Reporter: igor-fbsdbugs@grinchenko.org reproducible in any 12.0-RELEASE. (11.2-RELEASE and older do not seem to ha= ve the issue) - run xterm or tmux, resize it to 75 or 76 or 77 columns (tried a few other sizes, seems to segfault only with these three) - run top, let it update 1-2 times - resize terminal wide (resizing narrow won't cause the segfault). for completeness here is the backtrace (not too useful without debug symbol= s, but still) # lldb -c top.core /usr/bin/top (lldb) target create "/usr/bin/top" --core "top.core" Core file '/root/top.core' (x86_64) was loaded.
