Crash
Waybar crashes frequently with the following error:
malloc(): unaligned tcache chunk detected
[1] 39455 IOT instruction (core dumped) waybar
If you need more information, please let me know how to provide it and I will try to do so.
Also note the following info:

I am willing to help, but I am not sure how to start. Can you give some quick pointers?
Like; should I build in debug mode... and how... are there other important pointers?
I also see frequent (one per couple of hours) crashes. A coredump shows that resizing a string (inside Ipc::recv) caused an abort. In another coredump the abort also occured in malloc, but with a completely different backtrace. Maybe there is some heap corruption taking place? I try to debug this further by tracing the allocations.

How did you generate that core dump? I would like to know the exact error for my issue (as well).
I also run Arch Linux which uses systemd. You can use coredumpctl and coredumpctl debug $PID to list coredumps and start gdb on the coredump. The command bt shows the backtrace in gdb. I think the systemd-coredump.socket is enabled per default, so you should have some coredumps recorded too.
This is my coredump:
Core was generated by `./waybar'.

This is a little over my head (I have zero experience with gtk programming). The main change I see is the new window icon support. So, I will first move forward and disable that and see if waybar becomes (more) stable:
"sway/window": {
"icon": false,
},
I have been having the same problems on the latest version of waybar (Waybar v0.9.10). I disabled window icon support as suggested and have had no issues. (Working 5+ hours without a crash)
Same problem but different "solution".
I'm on Waybar v0.9.9
I did use the default config as a starting point and everything worked perfectly and looked good except for the backlight icons.
OTF icons are installed and displayed correctly for anything else.
Removing the icons from the backlight module "fixed" it for me.
Core dumb:
Core was generated by `waybar -b bar-0'.
Program terminated with signal SIGTRAP, Trace/breakpoint trap.

Well, never mind. Just build from scratch and it is not reproducible anymore.
