Segmentation Fault: 11 seen when running mdbook on Rust RFCs

I'm trying to build a book for rust RFCs. Running mdbook results in segmentation fault. Ran mdbook with valgrind, and here's the output.

I believe this issue is caused by rust-lang/rust#51758. Please try building mdbook with the latest nightly to see if it fixes the issue.

Yup. Does the trick. Thanks!
