Issue with custom .bash_profile on macOS

[rm-code]

sb-exec seems to produce an error at the startup of Atom Editor if I have the following content in my .bash_profile:

function foo() {
    ~/bar "$@"
}
export -f foo

txtblu='\e[0;34m'
txtpur='\e[0;35m'
txtrst='\e[0m'   

printf "\n$txtblu%s @ $txtblu%s $txtpur%s\n$txtrst" "$USER" "$PWD"

I originally thought it was a problem with AtomLinter, but was forwarded to the exec repository instead. The error log comes from Atom Editor, so I'm not sure if it actually helps:
