Temporary value dropped while borrowed

[Javantea]

Bug description

Using nightly rust build failed. I got this error and more like it running cargo build.

error[E0716]: temporary value dropped while borrowed

     |         borrow later used here

     = note: consider using a `let` binding to create a longer lived value
