emacs: raw strings containing " break syntax highlighting

[tomjakubowski]

A raw string like this breaks highlighting as well as indentation (upon indenting an error about unbalanced parentheses appears):

In the lower split I worked around it for the following lines by ending the line with // ";

@tomjakubowski What version of emacs are using using?
I am using GNU Emacs 25.0.50.1 (x86_64-apple-darwin14.0.0, NS appkit-1343.14 Version 10.10 (Build 14A389)) of 2014-10-23 and it indents fine for me.
Can you also provide a screenshot of the error on unbalanced parantheses?

#10190 is related.

I'm using GNU Emacs 24.4.1 (x86_64-pc-linux-gnu, GTK+ Version 3.14.3) of 2014-10-26 on trouble, modified by Debian and the following is stable under reindentation and causes emacs to emit up-list: Scan error: "Unbalanced parentheses", 35, 1:

fn main() {
    let r#" " "#;
foo()
}
