Please note that these warnings are just used to help the Homebrew maintainers
with debugging if you file an issue. If everything you use Homebrew for is
working fine: please don't worry or file an issue; just ignore this. Thanks!

Warning: Some installed formulae are deprecated or disabled.
You should find replacements for the following formulae:
  packer
  vault

Warning: You have unlinked kegs in your Cellar.
Leaving kegs unlinked can lead to build-trouble and cause formulae that depend on
those kegs to fail to run properly once built. Run `brew link` on these:
  numpy

Verification

• My brew doctor output says Your system is ready to brew. and am still able to reproduce my issue.
• I ran brew update and am still able to reproduce my issue.
• I have resolved all warnings from brew doctor and that did not fix my problem.
• I searched for recent similar issues at https://github.com/Homebrew/homebrew-core/issues?q=is%3Aissue and found no duplicates.

What were you trying to do (and why)?

I was trying to compile and run koboldcpp https://github.com/LostRuins/koboldcpp.

What happened (include all command output)?

The following python snippet segfaults. This for both [email protected] and [email protected]

import tkinter
import threading

original_windowwidth = 580
original_windowheight = 560
windowwidth = original_windowwidth
windowheight = original_windowheight

root = tkinter.Tk()
root.geometry(str(windowwidth) + "x" + str(windowheight))
gpu_choice_var = tkinter.StringVar(value="1")
quick_gpuname_label = tkinter.Label(root, text="hello")

def outPrint(*args):
    quick_gpuname_label.configure(text="1")
    print(args)
gpu_choice_var.trace_add("write", outPrint)

gpuinfo_thread = threading.Thread(target=outPrint)
gpuinfo_thread.start()

# gpu_choice_var.set("1")
# outPrint()
# root.mainloop()

What did you expect to happen?

segmentation fault to not happen.

This problem came up due to the recent change from tcl 8.x to tcl 9.0.0 as the default tcl package.
I am not sure where in the segfault issue is from
