--- Comment #1 from Zhendong Su <su at cs dot ucdavis.edu> ---
Below is a simpler testcase that should demonstrate the same issue:
----------------------------------
int printf (const char *, ...);
int a, b[2];
int
main ()
{
for (a = 1; a >= 0; a--)
{
b[1] = 1;
b[a] = 0;
}
if (b[1] != 1)
__builtin_abort();
return 0;
}
