From above thread:
Indeed, changing abort() to invalid memory reference makes backtrace work.
foo (int a, int b)
{
int c=40;
abort(); <--- IIUC, change to invalid memory reference
return a+b;
}
I don't know whether can remove the __attribute__((noreturn)) or not
when compiling glibc. It seems the problem a little complicated....
