debugger trap with angr

Question

Let's suppose this (very ugly) c code:

#include <stdio.h>
#include <string.h>
#include <signal.h>

char sav_argv[100];

void on_sigtrap(int signo)
{
    if (strcmp(sav_argv, "hello") == 0)
    {
        printf("OK!\n");
    } else {
        printf("NOK\n");
    }
}

int main(int argc, char *argv[])
{
    memset(sav_argv,100,0);
    memcpy(sav_argv,argv[1],100);
    signal(SIGTRAP,on_sigtrap);
    __asm__("int3");
    return 0;
}

I have compiled this c program with gcc (linux 64 bits elf).

What i want to do is to solve it with an angr python script. It does work if i remove the debuger trap but it does not work with debuger trap.

Is there a way to make angr work on this c program ?

Thanks
