[Bug]: Problem when I change font in Conky

[neecride]

What happened?

Hello, I'm trying to build a nice desktop but I have this error which prevents Conky from refreshing and I don't understand Linux enough to correct the problem

/usr/include/c++/13.2.1/bits/stl_vector.h:1125: std::vector<_Tp, _Alloc>::reference std::vector<_Tp, _Alloc>::operator[](size_type) [with _Tp = x_font_list;
_Alloc = std::allocator<x_font_list>;
reference = x_font_list&;
size_type = long unsigned int]: Assertion '__n < this->size()' failed.

Version

1.18.1-2

Which OS/distro are you seeing the problem on?

Arch Linux (Archcraft)

This seems to be the same error message as in https://github.com/brndnmtthws/conky/issues/1538#issuecomment-1565390136. (Using version 1.19.4+ may fix the issue according to some comments there; Arch's main repo seems to be behind and is still on 1.18.1.)

Issue likely in font command. Index out of bounds error. Definitely a bug because conky shouldn't crash, even if you use non-existant font.
