>             Project: ORC
>          Issue Type: Bug
>          Components: C++
>    Affects Versions: 1.9.0, 1.8.1

> When building the C++ library on a platform where char is by default unsigned, byte-to-integer expansion is incorrect in orc::expandBytesToIntegers as well as in a few unit tests.
> This can be reproduced on any CPU architecture when building with gcc by compiling with -funsigned-char.
