Reduced testcase as follows:
static void b2w(unsigned int *out, const unsigned char *in, unsigned int len)
{
const unsigned char *bpend = in + len;
for (; in != bpend; in += 4, ++out)
{
*out = (unsigned int) (in[0] ) |
(unsigned int) (in[3] << 24);
}
}
static void md4step(unsigned int state[4], const unsigned char *data)
{
unsigned int A, X[16];
b2w(X, data, 64);
state[0] += A;
}
void md4sum(void)
{
unsigned char final[128];
unsigned int state[4];
md4step(state, final);
md4step(state, final + 64);
}

Re-open. Still a 4.5 regression (please close bugs only when they are fixed

patch for fixing this PR.
