Arch Linux

Description:

After the last rolling update of Manjaro packages, powertop-2.10-1 exits with a segfault on startup. I am reporting this here because this is unlikely to have anything to do with Manjaro-specific packaging (powertop comes from Arch repos), and also because I haven't been able to find a way to create an account in Powertop's bug tracker (https://us-bz3.devzing.com/powertopbugs/).

I rebuilt powertop with options=(debug !strip) and ran sudo gdb powertop. Here is the relevant part of the output:
