Rofi modi scripts terminating with SIG SEGV (Address Boundary Error)

I have a rofi config file as such below:

configuration
{
	modi: "Home:~/.config/rofi/search-home.sh, Storage:~/.config/rofi/search-storage.sh"
	font: "Comic Sans MS Bold 14";
	show-icons: true;
	icon-theme: "candy-icons";
	matching: "normal";
	hover-select: false;
	me-select-entry: "";
	me-accept-entry: [ MousePrimary ];
}
@theme "~/.config/rofi/themes/search.rasi"

and here are the two bash scripts for the respective modi

Home script:

#!/bin/bash

opener="xdg-open"

if [[ -z "$1" ]]; then
    fd . --hidden $HOME 2>/dev/null | sed "s;$HOME;~;g"
else
    selection=$(echo "$1" | sed 's;\~;$HOME; ;s/ /\\ /g; s/\&/\\&/g; s/(/\\(/g; s/)/\\)/g')
    eval $opener "$selection" > /dev/null 2>&1 &
fi

Storage script:

#!/bin/bash

opener="xdg-open"

if [[ -z "$1" ]]; then
    fd . --hidden /mnt/Storage 2>/dev/null
else
    selection=$(echo "$1" | sed 's/ /\\ /g; s/\&/\\&/g; s/(/\\(/g; s/)/\\)/g')
    eval $opener "$selection" > /dev/null 2>&1 &
fi

run command:

rofi -config ~/.config/rofi/search-config.rasi -show Home -sort -sorting-method fzf -i -debug

after running the command, the issue is that when I have something in my prompt and I try to change the rofi modi using the ctrl + tab keybinding rofi gets terminated by SEGV signal

"rofi -config ~/.conf…' terminated by signal SIGSEGV (Address boundary error)"

I have tried with different prompt strings, but it always gets terminated when changing modi a few times. I am not able to figure out what is causing this memory error.
Please help
Thank you <3

Re: Rofi modi scripts terminating with SIG SEGV (Address Boundary Error)

Managed to only capture this with the gdb, the laptop just freezes when it encounter the error, then I need to hard reboot using power button.

Re: Rofi modi scripts terminating with SIG SEGV (Address Boundary Error)

Please replace the oversized image w/ a link (the board has a 250x250px max rule) but w/o the backtrace, that's useless anyway.

the laptop just freezes when it encounter the error

That's not part of you OP?

then I need to hard reboot using power button.

Can you still switch to a different TTY (ctrl+alt+F2,F3,F4,…)?

Re: Rofi modi scripts terminating with SIG SEGV (Address Boundary Error)

Yes I can access the tty3 with the keybinding, but how does it help I can't get the log of the gdb that was running in the terminal, as the system freezes I can't write that info into a file.

Re: Rofi modi scripts terminating with SIG SEGV (Address Boundary Error)

It means the system isn't frozen.
If you run a process in gdb it'll stall and you'll have to "continue" it first.
If that's not it, the obvious alternative would be to attach gdb to the rofi process on tty3 (so you're debugging on the console and not in the GUI session)

Re: Rofi modi scripts terminating with SIG SEGV (Address Boundary Error)

But rofi is a gui application how will it run on tty?

Re: Rofi modi scripts terminating with SIG SEGV (Address Boundary Error)

You still run rofi on the GUI, you just attach gdb to it on the TTY.
Incidentally, I assume the only thing that happens is that rofi grabs the input, gets stalled by gdb and now you've a stalled input grab.
Try if you can replicate the crash when running rofi as "-normal-window" which will prevent the grab.

Re: Rofi modi scripts terminating with SIG SEGV (Address Boundary Error)

Okay so this is what I did

First I ran the previously mentioned rofi command with -normal-window option and it worked fine the rofi window showed up with the prompt, then I switched to TTY and logged into my profile, and ran htop found the rofi PID, I quit the htop, and did sudo gdb -p <rofi-pid>, then I switched back to the GUI and found that my rofi window is stalled I am not able to input anything to replicate the error.

Re: Rofi modi scripts terminating with SIG SEGV (Address Boundary Error)

Okay so since I was able to use the GUI when running the rofi in the normal window mode, I opened up a terminal and did what as instructed here and was able to get the trace log

Rofi is included in https://wiki.archlinux.org/title/Debuginfod what should give you a more readable backtrace (notably function symbols)

Re: Rofi modi scripts terminating with SIG SEGV (Address Boundary Error)

        fstate = 0

the add_list nullptr looks incredibly suspicious.
