SUMMARY
***
NOTE: If you are reporting a crash, please try to attach a backtrace with debug symbols.
See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports
***


STEPS TO REPRODUCE
1. compile the below demo program with debug (-g) using cross compiler. 
#include <stdio.h>
#include <sys/select.h>

/* According to earlier standards */
#include <sys/time.h>
#include <sys/types.h>
#include <unistd.h>
#include <fcntl.h>
#include <errno.h>
#include <string.h>
#include <sys/socket.h>
#include <netinet/in.h>
#include <arpa/inet.h>
#include <stdlib.h>
#include <sys/types.h>          /* See NOTES */
#include <sys/socket.h>


void func_888()
{
    printf("hello world\n");
    return;
}

void func_666()
{
	printf("你好 世界\n");
	return;
}

int main(int argc, char *argv[])
{
    while(1)
    {
        func_888();
	printf("blabla...\n");
	func_666();
	usleep(10);
    }
    return 0;
}

2. using callgrind tool to run the demo: valgrind --tool=callgrind ./a.out
3. using kcachegrind to check the result.

OBSERVED RESULT
I did not get a right call graph, but it was right on x86_64. The wrong result named aarch64.png is attached.

EXPECTED RESULT
The right result named x86_64.png is attached.
