typedef unsigned int uint32_t;
uint32_t g_330;
uint32_t
func_45 (uint32_t p_47)
{
for (p_47 = 0; (p_47 < 22); ++p_47)
{
if (p_47)
{
func_70 (1);
}
else
g_330 = 1;
}
func_56 (func_95 (p_47));
}

[regehr]

Slightly cleaner version of this testcase.

int g_330;

void func_45 (int p_47)
{
for (p_47 = 0; p_47 < 22; ++p_47)
{
if (p_47)
func_70 ();
else
g_330 = 1;
}
func_95 (p_47);
}
