Bug ID: 15870
Summary: backtrace don't give same result when called between
redhat-32bit and redhat-64bit
Product: glibc
Version: 2.18
Status: NEW
Severity: normal
Priority: P2
Component: localedata
Assignee: unassigned at sourceware dot org
Reporter: stigano at 163 dot com
CC: libc-locales at sourceware dot org
code:
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <signal.h>
#include <execinfo.h>
#include <fcntl.h>
#include <unistd.h>
void coredump_handle(int sig)
{
void *arraypoint[100];
size_t size;
size = backtrace(arraypoint,100);
return;
}
void core()
{
int i,j;
i=0,j=1;
printf("j/i=[%d]\n",j/i);
}
void test()
{
core();
}
void core_test()
{
test();
int a,b;
a=1,b=2;
a= b;
}
int main()
{
int i,j;
signal(SIGFPE,coredump_handle);
core_test();
i=0,j=1;
i++;
return 0;
}
this code run on redhat 32it cannot locate the line where cause coredump,only
locate the line the function called,but on redhat 64-bit do locate the line
cause coredump.
in functon coredump_handle,if the result of size is n on the 32-bit os,the
result of size always to be n-1.
