Using the emacs-26 branch from the git.savannah.gnu.org/emacs.git repository. Emacs is segfaulting when I run the command 'M-x package-list-packages'. This is the backtrace: (gdb) bt full #0 0x0000003d5c6e34c1 in __res_vinit () from /lib64/libc.so.6 No symbol table info available. #1 0x0000003d5c6bc59c in gaih_inet () from /lib64/libc.so.6 No symbol table info available. #2 0x0000003d5c6be95a in getaddrinfo () from /lib64/libc.so.6 No symbol table info available. #3 0x00002aaaab01720a in handle_requests () from /lib64/libanl.so.1 No symbol table info available. #4 0x0000003d5ce0683d in start_thread () from /lib64/libpthread.so.0 No symbol table info available. #5 0x0000003d5c6d4fdd in clone () from /lib64/libc.so.6 No symbol table info available.
