Maybe set to to an ASCII integer like this:
```
static const uint32_t LLDB_FLAG = 'LLDB';
```
Then we check if the `exp_record.ExceptionFlags` is equal to LLDB_FLAG, we are sure this is an LLDB thing. We don't want to load something from a different minidump creator and just assume since the high bit is set that it is a LLDB exeption. Or we can leave `exp_record.ExceptionFlags` alone and encode this 'LLDB' as the first item in the `exp_record.NumberParameters` args and then append anything else we need to encode.
