Confirmed. Reduced testcase (compile with -O3):
================================================================
int foo();
void bar()
{
int N, i, j, k, *p;
if (i)
while (1)
{
while (N)
{
for (i = 0; i < N; i++)
for (; p; ++p)
for (j = 0; j < N; j++)
switch (N)
{
case 1:
++k;
case 2:
break;
case 3:
++k;
case 4:
++k;
case 5:
++k;
default:
k = foo();
}
if (foo()) break;
}
if (foo()) break;
}
}
================================================================
