No. In the code you quoted from Fpurecopy symbol is only put in
Vpure_uninterned_symbol_table when it is uninterned _at the time
of the purecopy_. Probably in this case it is interned at that time
(although I do not know how).
I agree the code you cited from bytecode.c looks correct. I also read
through it when hunting fro this bug.

You mean Kyle?
I was replying to a message from Gunnar in the bug tracking archive where
he asks the bug reporter to try it with 21.2 because Martin had
touched the relevant code.

If you unintern it later, it doesn't matter, because you still have a
living reference in Vpure_uninterned_symbol_table, which should keep
the GC sweeper from putting its greasy hands on the symbol.
No. That reference exists only if it was uninterned before.
I still think that is the best explanation for the crash, giving the symptoms.
