Hi, friends! Conky crashes with segfaults.

Arch Linux. Conky build g27ae07c2.

Can we get /home/vis/.config/conky/conky.conf too? Or narrow this config down to object/variable.

[BytEvil]

Here is my conky.conf

[lasers]

I need the file from this too. :relaxed:

    lua_load = '/home/vis/.config/conky/settings.lua',
    lua_draw_hook_post = 'main',

[BytEvil]

Ok! :)) Here is my settings.lua content.

[lasers]

For your information, hcitool is deprecated. Your setting.lua requires more Lua files located in a certain Lua directory so I give up on narrowing this config down to object/variable. Sorry. :-)

[BytEvil]

hcitool worked fine in my conky config since 2015 up to conky git version gfc250d80 ;)
lua1-graphs.lua
lua2-text.lua
lua3-bars.lua

P.S.: conky segfaults after commit 594d0c8.

Conky has also been segfaulting for me after upgrading to v1.11.4 . Commenting out the "${memgraph} " section here https://gist.github.com/cinnaboot/91b82d68fc2be4829f4434e5207d92e2 seems to skip the offending codepath.

Edit) also on Arch linux

I also get segmentation faults on Arch Linux, minimal conkyrc to reproduce:

conky.config = {
  background = false,
  use_xft = true,
  font = 'mononoki:size=7',
  own_window_class = 'conky',
  double_buffer = true,
};

conky.text = [[
${cpugraph cpu1 20,137 23a51c ff661c -t}
]];

There's a PR #858 to fix a memory leak that was introduced in that commit. Does that fix also fix the segfault?

Fixed. Please merge. ;)

Closed via #858.
