Select WILDCARD --> Unexpected code path Exception

[GoogleCodeExporter]

With 1.4 branch he following query fails:

select a1.*
from
    risk.instrument a1
    inner join (
        select a.*
        from risk.INSTRUMENT a
            inner join risk.counterparty b
                on b.id_counterparty=a.id_counterparty
                    and b.id_status='C'
            left join risk.EXECUTION_INSTRUMENT ex 
                on a.ID_INSTRUMENT_REF=ex.ID_INSTRUMENT_REF 
        where
            a.id_status='C'
            and a.fair_value<0
            and ex.ID_EXECUTION_REF is null
    ) b 
        on a1.id_counterparty=b.id_counterparty
            and a1.id_status='C'

However, when defining certain fields instead of using the wildcard, it works:

select a1.id_instrument
from
    risk.instrument a1
    inner join (
        select a.*
        from risk.INSTRUMENT a
            inner join risk.counterparty b
                on b.id_counterparty=a.id_counterparty
                    and b.id_status='C'
            left join risk.EXECUTION_INSTRUMENT ex 
                on a.ID_INSTRUMENT_REF=ex.ID_INSTRUMENT_REF 
        where
            a.id_status='C'
            and a.fair_value<0
            and ex.ID_EXECUTION_REF is null
    ) b 
        on a1.id_counterparty=b.id_counterparty
            and a1.id_status='C'
--> 23 rows selected

Please note, that the same query worked well with 1.3 branch.

[GoogleCodeExporter]

Fixed in Revision r6016

Log message

In version 1.4.184, a bug was introduced that broke queries that have both joins
and wildcards, for example: select * from dual join(select x from dual) on 1=1
