Running sudo (tested 1.8.20_p2, 1.8.22-r2 and 1.8.23) results in a segfault: $ gdb /usr/bin/sudo $ (gdb) r Starting program: /usr/bin/sudo Program received signal SIGSEGV, Segmentation fault. 0x00005594f5d70bd8 in get_user_info (ud=0x5594f5f7eb20 <user_details>) at ./sudo.c:541 541 ud->sid = getsid(0); (gdb) I've re-compiled gcc (6.4), glibc and binutils without success. Reproducible: Always Steps to Reproduce: 1. Emerge sys-libs/glibc-2.26-r7 2. Re-emerge sudo 3.
