    expressions: Parse multiple sets of parentheses for grouping together.
    Fuzzers are fond of driving expression parsers to failure by exhausting
    the stack in trivial ways.  This defeats the simplest attempts by
    lining up thousands of left parentheses in a row.
    I am a bit curious whether the fuzzer will now invent something more
    sophisticated, such as nested function calls or non-empty expressions like
    This fixes bug #61286.
    Thanks to Irfan Ariq for reporting the bug.
