Looks like this version affects all ruby versions, though I tested only on 2.4.2 and trunk. ---------------------------------------- Bug #14231: __uint128_t check in hash.c is broken, use https://bugs.ruby-lang.org/issues/14231#change-68636 * Author: bircoph (Andrew Savchenko) * Status: Open * Priority: Normal * Assignee: * Target version: * ruby -v: * Backport: 2.3: UNKNOWN, 2.4: UNKNOWN, 2.5: UNKNOWN ---------------------------------------- Current check for __uint128_t in hash.c is not valid, since it ignores compilers other than gcc. We hit this on lcc on e2k platform. Configure script properly checks from 128-bit data types support and sets HAVE_UINT128_T accordingly. This approach is already used within ruby at bignum.c, random.c, etc. Probably hash.c is an overlooked remnant of old days. This patch fixes this.
