Do gdb /bin/conky (if that's the path to conky on your system)
Understood and my mistake. Sorry.
Then, instead of run -c [etc.]
I am unsure I understand. Obviously I will replace the pseudo-path that is within the angle-brackets.
I am not on the affected computer right now. But that does all me to add the following. The earlier version of Conky on which I do not have the problem advertises itself (within my Conky itself) as 1.19.8_pre.
from conky.

The latest iteration of version 1.21.1 (the iteration advertised here) seems to fix this problem. Great!
EDITED.

You didn't start gdb with conky executable nor attached it later. Do gdb /bin/conky (if that's the path to conky on your system). Then, instead of run -c <full-path-of-my-conkyRC> actually replace <full-path-of-my-conkyRC> with a path to (one of) your conky configuration file(s).

Caused by PR introducing geometry primitives #1862.
The cause is _member_access having invalid pointer to Container (rect<int>).
Line that crashes:
window.window = XCreateWindow(display, window.root, window.geometry.x,
window.geometry.y, b, b, 0, depth,
InputOutput, visual, flags, &attrs);on window.geometry.x because this from x _member_access is invalid.
My hunch is this gets moved and so the pointer is invalid.
Reproduced by reloading the config.
Currently trying the following to fix this: update those pointers on move and move assignment.

So the problem is that I tried being too clever with the dark arts of metaprogramming and missed that assignment to nested rect member (pos in this case) makes it impossible to update rect _member_access.
The previously proposed fix would require additional metadata at which point the rect struct would store more metadata than actual data, just to provide a bit more convenient syntax. For stored members the metadata can't be erased so the benefit is not worth the cost.
So I'm removing _member_access.

@LinuxOnTheDesktop I was able to reproduce and can't anymore after fix/geometry-accessors. Can you confirm it's fixed?

I am afraid that the problem is not fixed. Here are some details.
I used git to obtain a version of conky that advertises itself as 1.21.0-pre-6bf383cf343. With that version modifying conkyrc crashes conky with a 'segmentation fault'.

Right. I think I've switched branch. (I'm not great at git.) Conky now advertises itself as 1.21.0-pre-6bf383cf.
I seem to have the same problem as before. For, the terminal reports that the config file was modified, and that consequently it is being reloaded, but then I still get a segementation fault. I can, later, supply another stack trace.

Alright, do let me know, because I was able to replicate and I believe the changes that got merged fixed the problem. If you're still seeing conky::_priv_geom::_member_access in the stack trace that means you're starting a wrong binary because _member_access was removed.
In any case, paste the new stack trace and I'll check it out.
