Parse errors not reported sometimes inside --cfg option #89358
Description
I tried this command:
rustc --cfg "abc\""
(note the lone stray quote passed at the end of the argument)
I expected to see this happen:
error: invalid `--cfg` argument: `abc"` (expected `key` or `key="value"`)
Instead, this happened: rustc exits with code 1, but with no output on stderr or stdout
