When using an enum value in an arithmetic operation LLDB promotes the resulting type to `unsigned int`, and not to the default underlying type `int`.
Source code with 2 variables with the results from a compiler:
```
enum UnscopedEnum { Zero, One };
int main() {
auto enum_one = UnscopedEnum::One;
auto negated = -enum_one;
auto added = enum_one + 1;
return 0;
}
```
LLDB log:
```
(lldb) expr negated
(int) $0 = -1
(lldb) expr added
(int) $1 = 2
(lldb) expr -enum_one
(unsigned int) $2 = 4294967295
(lldb) expr enum_one + 1
(unsigned int) $3 = 2
```
If the enum type is explicitly specified `enum UnscopedEnum : int`, then the promotion works correctly.
