create a ptrdiff_t offset between the start of an allocation region and some interesting pointer, so it can be adjusted with this offset after realloc() returns. for pdisk(), realloc() is a locally inlind malloc() and free() pair. for mail(1), this required a little bit more effort as the old pointer was passed into another file for fix-ups there, and that code needed to be adjusted for offset vs old pointer usage. found by GCC 12. |
