After upgrading to glibc-2.27 and rebuilding @world, Tor crashes right after being started with a message like this: ============================================================ T= 1528983902 (Sandbox) Caught a bad syscall attempt (syscall openat) tor(+0x1921da)[0x56009de401da] /lib64/libpthread.so.0(open64+0x4b)[0x7f24bc48a1db] /lib64/libpthread.so.0(open64+0x4b)[0x7f24bc48a1db] tor(tor_open_cloexec+0x40)[0x56009de26a10] tor(start_writing_to_file+0x16a)[0x56009de3a5aa] tor(+0x18c68b)[0x56009de3a68b] tor(+0x18c7d8)[0x56009de3a7d8] tor(or_state_save+0x151)[0x56009dd666e1] tor(+0x5099d)[0x56009dcfe99d] tor(+0x6c0e1)[0x56009dd1a0e1] tor(rescan_periodic_events+0x111)[0x56009dd01271] /usr/lib64/libevent-2.1.so.6(+0x226bd)[0x7f24bd8966bd] /usr/lib64/libevent-2.1.so.6(event_base_loop+0x4e7)[0x7f24bd897377] tor(do_main_loop+0x17a)[0x56009dd028fa] tor(tor_run_main+0x1015)[0x56009dd04ce5] tor(tor_main+0x3a)[0x56009dcfd17a] tor(main+0x19)[0x56009dcfcf09] /lib64/libc.so.6(__libc_start_main+0xe7)[0x7f24bc0d09f7] tor(_start+0x2a)[0x56009dcfcf5a] It's triggered by having "Sandbox 1" in the torrc. It's always worked perfectly before and rebuilding it doesn't help.
