someone, show me some intelligence:

What is wrong with the following code?
This was from an interview.
(Now RFC 3092 compliant).

int* head = 0;
int* tail = 0;

struct foo{

int bar;
int *pNext;

}baz;

insert ( int qux ) {
baz* quux;

quux = malloc( sizeof(baz) );
quux->bar = qux;
if (head == tail ) {
head = quux;
tail = quux;
}

/* rest of insert */
}
