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.
