V560 A part of conditional expression is always true: !pSymbolList.

In commit a2cd17d1, pSymbolList and
xSymbols were made non-static. The check below was left though.

Actually, I don't know if that was a safe move, since it's unclear
how the lifetime of the returned pointer is managed now to prevent
use-after-free.
