error: invalid `--cfg` argument: `)` (expected `key` or `key="value"`)
Emit an error for `--cfg=)` Fixes #73026 See also: #64467, #89468 The issue stems from a `FatalError` being silently raised in `panictry_buffer`. Normally this is not a problem, because `panictry_buffer` emits the causes of the error, but they are not themselves fatal, so they get filtered out by the silent emitter. To fix this, we use a parser entrypoint which doesn't use `panictry_buffer`, and we handle the error ourselves. 2022-01-01 05:12:56 +01:00			error: invalid `--cfg` argument: `)` (expected `key` or `key="value"`)
