The error was not thrown by the buffer-local-value function.  It was
thrown by eval, trying to (recursively) evaluate the fundamental-mode
form, whose result it would then pass as the first argument
buffer-local-value.

You have demonstrated that the major-mode symbol has its value cell set
to the fundamental-mode symbol, and several other facts about the
major-mode symbol.  You have not demonstrated any facts about the
fundamental-mode symbol.
