Codes: if (FilePosition + ExtentLength > ReadFileInfo->FilePosition) { Offset = ReadFileInfo->FilePosition - FilePosition; if (Offset < 0) { Offset = -(Offset) } ... } offset is UINT64 can not < 0, so the code logic may have some issue. and Offset = -(Offset) may build failure in some circumstance. previously type case Offset to INT64 to fix build block. Now remove the type cast. Then can to check the code logic later.
