rust-gdbgui shell script crashes due to improper string quoting

[real-eren]

I tried this code:

rust-gdbgui $my_executable

I expected to see this happen: gdbgui starts

Instead, this happened: (dash) shell error
/home/eren/.rustup/toolchains/stable-x86_64-unknown-linux-gnu/bin/rust-gdbgui: 58: -iex "add-auto-load-safe-path /home/eren/.rustup/toolchains/stable-x86_64-unknown-linux-gnu/lib/rustlib/etc": not found
