error: aborting due to previous error
Fix bug in shebang handling Shebang handling was too agressive in stripping out the first line in cases where it is actually _not_ a shebang, but instead, valid rust (#70528). This is a second attempt at resolving this issue (the first attempt was flawed, for, among other reasons, causing an ICE in certain cases (#71372, #71471). The behavior is now codified by a number of UI tests, but simply: For the first line to be a shebang, the following must all be true: 1. The line must start with `#!` 2. The line must contain a non whitespace character after `#!` 3. The next character in the file, ignoring comments & whitespace must not be `[` I believe this is a strict superset of what we used to allow, so perhaps a crater run is unnecessary, but probably not a terrible idea. 2020-04-23 14:51:12 -05:00			error: expected `[`, found `B`
