Summary: Dictionary <K,V> goes into infinite loop trying to
retrieve a value
Classification: Mono

When debugging some moonlight websites I came across a bug in Dictionary<K, V>
where it would go into an infinite loop in this code:
while (cur != NO_SLOT) {
// The ordering is important for compatibility with MS and strange
// Object.Equals () implementations
if (linkSlots [cur].HashCode == hashCode && hcp.Equals (keySlots [cur],
key)) {
value = valueSlots [cur];
return true;
}
cur = linkSlots [cur].Next;
}
linkSlots[cur].Next is returning the same value as 'cur', so we loop forever
checking the same slot. If it's important, the dictionary in question was a
Dictionary<IntPtr, ToggleRef> from Moonlight.
