Homu	02c4ff7b7e	Auto merge of #594 - serde-rs:expr, r=oli-obk No longer need `e!` This compiles all the way back to Rust 1.7.0, and 1.6.0 fails for other reasons so I think we are clear here. The referenced issue https://github.com/rust-lang/rust/issues/19630 is still open so they must have fixed it some other way.	2016-10-19 18:07:10 +09:00

David Tolnay	1d719b542c	Not safe to share Spans from one ParseSess to another Spans in the AST returned by `parse_item_from_source_str` and other parsing functions contain byte offsets into the source code they were parsed from. The pretty printer uses these Spans [here][1] to preserve the representation of literals when parsing and printing back out unmodified. In this bug, the byte offset of a string in the input to `parse_item_from_source_str` coincidentally matched the byte offset of a totally different string in the input to `parse_crate_from_file` called [here][2] by Syntex. The Span from the former triggered the pretty printer to write out the content of the latter. By using the same ParseSess, Spans from the two `parse_*` calls never collide.
