            Bug ID: 24972
           Summary: Error when working with pointers
           Product: clang
           Version: 3.6
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: Driver
          Assignee: unassignedclangbugs at nondot.org
          Reporter: dvshapkin at mail.ru
                CC: llvm-bugs at lists.llvm.org
    Classification: Unclassified

Ubuntu clang version: 3.6.0-2ubuntu1

strange error in a simple example...

int main(void)
{
    const int num = 1;
    int *p = #       //warning - ok

    printf("num = %d,  &num = %p\n", num, &num);   // num == 1, ok
    printf("*p  = %d,  p    = %p\n",  *p, p);      // *p == 1, ok

    *p = 2;

    printf("num = %d,  &num = %p\n", num, &num);   // num == 2, but see output
    printf("*p  = %d,  p    = %p\n",  *p, p);      // *p == 2, ok

    return 0;
}

<b>Output:</b>

num = 1,  &num = 0x7ffe479d91e8
*p  = 1,  p    = 0x7ffe479d91e8
num = 1,  &num = 0x7ffe479d91e8   <--- why num == 1 ???   must be num == 2
*p  = 2,  p    = 0x7ffe479d91e8
