It seems it crashes during futex syscall:
...
[pid 4] getpid() = 4
[pid 4] tgkill(4, 24, SIGRT_1) = 0
[pid 24] <... futex resumed> ) = ? ERESTARTSYS (To be restarted if
SA_RESTART is set)
[pid 24] --- SIGRT_1 {si_signo=SIGRT_1, si_code=SI_TKILL, si_pid=4,
si_uid=0} ---
[pid 4] futex(0x7f77abb4f610, FUTEX_WAIT_PRIVATE, 16777216, NULL
<unfinished ...>
[pid 24] getpid() = 4
[pid 24] --- SIGSEGV {si_signo=SIGSEGV, si_code=SEGV_MAPERR, si_addr=0x10}
---
...
