C11 6.5.6.9 says: When two pointers are subtracted, both shall point to elements of the same array object, or one past the last element of the array object; the result is the difference of the subscripts of the two array elements. In these cases the objects are arrays of char so the result is defined, and we believe that the report is based on a compiler incorrectly trapping on defined behaviour. Cast pointers to uintptr_t to avoid potential signedness errors. 2016-10-14T18:19:04+00:00 dtucker 2016-10-14T18:19:04+00:00 urn:sha1:334be4776e9619a5a075173d94155d509f240f3e Based on patch from yuanjie.huang at windriver.com via OpenSSH bz#2608, with & ok millert, ok deraadt.
