Guard against overflow in `codemap::span_to_lines`. (Revised/expanded version of PR #24976) Make `span_to_lines` to return a `Result`. In `diagnostic`, catch `Err` from `span_to_lines` and print `"(unprintable span)"` instead. ---- There a number of recent issues that report the bug here. See e.g. #24761 and #24954. This change *might* fix them. However, that is *not* its main goal. The main goals are: 1. Make it possible for callers to recover from an error here, and 2. Insert a more conservative check, in that we are also checking that the files match up. ---- As a drive-by, fix #24997 , which was causing my attempts to `make check-stage1` on an `--enable-debug` build to fail. |
