Here's another testcase for the same bug, or one closely related to it:
#include <stdio.h>
unsigned x = 8;
unsigned *addr()
{
return &x;
}
int main()
{
x = 4;
*addr() = *addr() / 2;
printf ("*addr() = %d, x = %d\n", *addr(), x);
return 0;
}
I've determined that both this test case and the original one reported with
this issue were fixed on mainline by the commit r119502, this patch:
http://gcc.gnu.org/ml/gcc-patches/2006-12/msg00225.html
I'm not familiar enough with this code (yet!) to be able to tell whether this
was a lurking bug fixed by that patch, or whether it is a lurking bug that was
merely obscured by that patch and is still present on mainline.
