Are you using any repos beyond the 3 basic ones (core, extra, community) ? Re-install gdb the "hard" way: pacman -Suy pacman -R gdb pacman -S gdb find /etc -iname "*.pac*" Verify dependencies: pacman -Qi gdb Verify: $ ls -al /usr/bin/gdb -rwxr-xr-x 1 root root 4634932 Aug 31 06:13 /usr/bin/gdb $ ldd /usr/bin/gdb linux-gate.so.1 (0xb77b0000) libreadline.so.6 => /usr/lib/libreadline.so.6 (0xb775b000) libdl.so.2 => /usr/lib/libdl.so.2 (0xb7756000) libncursesw.so.5 => /usr/lib/libncursesw.so.5 (0xb76f7000) libz.so.1 => /usr/lib/libz.so.1 (0xb76e0000) libm.so.6 => /usr/lib/libm.so.6 (0xb769a000) libpthread.so.0 => /usr/lib/libpthread.so.0 (0xb767d000) libpython2.7.so.1.0 => /usr/lib/libpython2.7.so.1.0 (0xb74e5000) libexpat.so.1 => /usr/lib/libexpat.so.1 (0xb74bc000) liblzma.so.5 => /usr/lib/liblzma.so.5 (0xb7495000) libc.so.6 => /usr/lib/libc.so.6 (0xb72e5000) /lib/ld-linux.so.2 (0xb77b1000) libutil.so.1 => /usr/lib/libutil.so.1 (0xb72e0000) $ Verify: $ cat /etc/gdb/gdbinit $ mv .gdbinit .gdbinit-save You can try debugging gdb itself first: $ gdb gdb or $ strace gdb jb
