The binary source is like

#include<stdio.h>
void go(char* name){
        char *ptr =name;
        printf("the name is %s\n",ptr);

}
int main(){
char thename[]="ohohohoho!\n";
printf("go home\n");
go(thename);
}

with compile options like "gcc ./src -o exe" the crashes come after inputing commands like below:

> r2 ./exe > aaa >s main >pdd
