Confirmed, reduced testcase (compile with -O2):
------------------------------------------------------------------------------
struct s
{
int a, b;
};
static int foo (struct s *u)
{
if (u->b == 0)
return 0;
foo1 (u);
u->b = 0;
return 0;
}
int bar (int j, char *fmt, struct s u)
{
int ch;
union
{
double d;
} d = { 0.0 };
if (j)
foo2 (j);
for (;;)
{
while (*fmt)
fmt += 1;
if (fmt)
if (++u.a)
if (foo (&u));
if (ch)
if (d.d)
if (++u.a);
}
return 0;
}
