Floating point exception(core dumped) when running wrapper script

[misterhackerman]

This is lfub file:

#!/bin/sh

# This is a wrapper script for lf that allows it to create image previews with
# ueberzug. This works in concert with the lf configuration file and the
# lf-cleaner script.

set -e

UB_PID=0
UB_SOCKET=""
UEBERZUG_TMP_DIR="/tmp"

cleanup() {
    exec 3>&-
    ueberzugpp cmd -s "$ub_socket" -a exit
}

if [ -n "$SSH_CLIENT" ] || [ -n "$SSH_TTY" ]; then
    lf "$@"
else
    [ ! -d "$HOME/.cache/lf" ] && mkdir -p "$HOME/.cache/lf"
    UB_PID_FILE="$UEBERZUG_TMP_DIR/.$(uuidgen)"
    ueberzugpp layer --silent --no-stdin --use-escape-codes --pid-file "$UB_PID_FILE"
    UB_PID=$(cat "$UB_PID_FILE")
    rm "$UB_PID_FILE"
    UB_SOCKET="$UEBERZUG_TMP_DIR/ueberzugpp-${UB_PID}.socket"
    export UB_PID UB_SOCKET
    trap cleanup HUP INT QUIT TERM EXIT
    lf "$@" 3>&-
fi

when i first boot the computer. it works successfully, after i close lfub, and then exit the terminal and start a new terminal and execute lfub I get this:

I don't know if i should include the coredump.
the issue is resolved by quitting dwm and starting again, i use startx. but then recreated by what I've provided earlier.
I use alacritty, dwm, arch linux.

[misterhackerman]

I could also reproduce it like this:
startx
launch alacritty
run ueberzugpp layer --silent --no-stdin --use-escape-codes --pid-file "file1"
close alacritty
launch alacritty
run ueberzugpp layer --silent --no-stdin --use-escape-codes --pid-file "file1"

Sorry it's a typo in the script $ub_socket instead of $UB_SOCKET.
