my weggli got hang while parsing a simple c source code.

[0xLucifer]

I install weggli use this command : cargo install weggli
and finally i can run weggli success.

this is the simple c code which i want to analyse with weggli

#include <stdio.h>
#include <string.h>
int main()
{
char array_1[16];
char array_2[16];
memcpy(array_1,array_2,16);
printf("Hello World!\n");
return 0;
}

and when I ran this command:
$ strace weggli '{printf(_);}' ./weggli.test.code -vvvvv

the strace command output last 10 lines here:

mmap(NULL, 2101248, PROT_NONE, MAP_PRIVATE|MAP_ANONYMOUS|MAP_STACK, -1, 0) = 0x7fb564dff000

mprotect(0x7fb564e00000, 2097152, PROT_READ|PROT_WRITE) = 0

rt_sigprocmask(SIG_BLOCK, ~[], [], 8) = 0

clone3({flags=CLONE_VM|CLONE_FS|CLONE_FILES|CLONE_SIGHAND|CLONE_THREAD|CLONE_SYSVSEM|CLONE_SETTLS|CLONE_PARENT_SETTID|CLONE_CHILD_CLEARTID, child_tid=0x7fb564fff910, parent_tid=0x7fb564fff910, exit_signal=0, stack=0x7fb564dff000, stack_size=0x1ffd80, tls=0x7fb564fff640} => {parent_tid=[11021]}, 88) = 11021

rt_sigprocmask(SIG_SETMASK, [], NULL, 8) = 0

futex(0x7fb56565e834, FUTEX_WAIT_BITSET_PRIVATE, 0, NULL, FUTEX_BITSET_MATCH_ANY^C) = ? ERESTARTSYS (To be restarted if SA_RESTART is set)

you can see it's stuck on the futex function.

when i run command : weggli '{printf(_);}' ./weggli.test.code -vvvvv

it's stuck here:

please help. thanks.
