> > I have a question regarding what offset should be used for storing? According to this [link](https://github.com/google/re2/issues/24#issuecomment-97653183) the offset can be achieved by pointer arithmetic. Is it safe to store in 32-bit space for a regular string array? > > What do you mean? The "start" field above would be an offset relative to the start of string, not a pointer. I mean, is it safe to minus two pointers from each other and cast the result from 64-bit to 32-bit? I know that the maximum range for a string array is 2 GB. I do not assume any special case. I just ask to sure that casting from 64-bit to 32-bit is safe. -- This is an automated message from the Apache Git Service.
