[SOLVED] gdb segmenation fault

Basically, gdb is not usable. Whenever I try to run gdb, there it fails with segmentation fault.

~ » gdb -v
[1]    320569 segmentation fault (core dumped)  gdb -v

This is the output of coredumpctl:

~ » coredumpctl gdb
           PID: 320569 (gdb)
           UID: 1000 (<redacted>)

I would be very grateful if anyone could help with this issue.

Re: [SOLVED] gdb segmenation fault

    Executable: /usr/local/bin/gdb

That's not where Arch installs gdb. Try /usr/bin/gdb and/or ask for help wherever you got that file.
