My, that's interesting. A look at nodes.h shows that 650 == T_Value,
which simply should not ever occur as a live node type. Unless my grep
is missing something, T_Value itself is never directly referenced
anywhere in the 8.3 source code. There are five occurrences of
makeNode(Value) but each of them immediately overwrites the node type
field with another type code such as T_Integer or T_String.

Not to put too fine a point on it, but I'm thinking "compiler bug".
You might try a build with the optimization level backed off to see
if the problem goes away.
