Bug ID: 48891
Summary: [clang-format] Different formatted output can be
produced from varying whitespace
Product: clang
Version: trunk
Hardware: PC
OS: All
Status: NEW
Severity: release blocker
Priority: P
Component: Formatter
Assignee: [email protected]

As of https://reviews.llvm.org/D93839, clang-format can produce different
formatted files depending on amount of whitespace. For example, given (A):
```
#include <stdint.h>
namespace fuzzing {}
```
`clang-format` with this patch would produced (B):
```
#include <stdint.h>
namespace fuzzing {
}
```
but given (C):
```
#include <stdint.h>
namespace fuzzing {
}
```
would be formatted to (D):
```
#include <stdint.h>
namespace fuzzing {
}
```
The invocation specifically is `clang-format --style=google file`. Prior to
this patch, both inputs (A/C) would give the same output:
```
#include <stdint.h>
namespace fuzzing {}
```
This seems to be unintended behavior that should be fixed. This doesn't seem to
occur if `#include "stdint.h"` is used.
