I've hit an unhandled exception when writing a query, and I'm curious if anyone here has seen the same thing. This is not a timeout issue - the error happens almost immediately, so it's not a query efficiency issue. The following query causes an "Internal Salesforce.com Error":
(Note that End_Client__c is an Account lookup on Opportunity, and accountIds is a Set<Id> of parents of both Account and End Client)

[
 SELECT Name
 FROM Account
 WHERE Id != :opp.AccountId
 AND Id != :opp.End_Client__c
 AND (
 Id IN :accountIds
 OR ParentId IN :accountIds
 OR Parent.ParentId IN :accountIds
 OR Parent.Parent.ParentId IN :accountIds
 OR Parent.Parent.Parent.ParentId IN :accountIds
 )
 ORDER By Name
]

However, it is fixed if I reduce the number of items in the OR chain to 2, regardless of which items I select. This means the merge fields are not the issue causing the error. The following works successfully:

[
 SELECT Name
 FROM Account
 WHERE Id != :opp.AccountId
 AND Id != :opp.End_Client__c
 AND (
 OR Parent.Parent.ParentId IN :accountIds
 OR Parent.Parent.Parent.ParentId IN :accountIds
 )
 ORDER By Name
]

I was fortunately able to find a workaround, which has left me even more confused. I changed the query to less efficient logic. The query below evaluates properly, which suggests to me that the query parser is failing.

[
 SELECT Name
 FROM Account
 WHERE (Id != :opp.AccountId
 AND Id != :opp.End_Client__c
 AND Id IN :accountIds)
 OR
 (Id != :opp.AccountId
 AND Id != :opp.End_Client__c
 AND ParentId IN :accountIds)
 OR
 (Id != :opp.AccountId
 AND Id != :opp.End_Client__c
 AND Parent.ParentId IN :accountIds)
 OR
 (Id != :opp.AccountId
 AND Id != :opp.End_Client__c
 AND Parent.Parent.ParentId IN :accountIds)
 OR
 (Id != :opp.AccountId
 AND Id != :opp.End_Client__c
 AND Parent.Parent.Parent.ParentId IN :accountIds)
 ORDER By Name
]

Can anyone shed some light on what is going on here?

After a bit of investigation with explicitly stated IDs, I think I found the unique issue that causes the error, and it can be handled more elegantly than my workaround.

Upon further investigation, the error is only happening when accountIds contains only opp.AccountId.

This fails:

[
 SELECT Name
 FROM Account
 WHERE Id != '0014000000SQyVGAA1'
 AND Id != null
 AND (
 Id IN ('0014000000SQyVGAA1')
 OR ParentId IN ('0014000000SQyVGAA1')
 OR Parent.ParentId IN ('0014000000SQyVGAA1')
 OR Parent.Parent.ParentId IN ('0014000000SQyVGAA1')
 OR Parent.Parent.Parent.ParentId IN ('0014000000SQyVGAA1')
 )
 ORDER By Name
]

This succeeds:

[
 SELECT Name
 FROM Account
 WHERE Id != '0014000000SQyVGAA1'
 AND Id != null
 AND (
 ParentId IN ('0014000000SQyVGAA1')
 OR Parent.ParentId IN ('0014000000SQyVGAA1')
 OR Parent.Parent.ParentId IN ('0014000000SQyVGAA1')
 OR Parent.Parent.Parent.ParentId IN ('0014000000SQyVGAA1')
 )
 ORDER By Name
]

And this also succeeds:

[
 SELECT Name
 FROM Account
 WHERE Id != '0014000000SQyVGAA1'
 AND Id != null
 AND (
 Id IN ('0014000000VqDVWAA3','0014000000SQyVGAA1')
 OR ParentId IN ('0014000000VqDVWAA3','0014000000SQyVGAA1')
 OR Parent.ParentId IN ('0014000000VqDVWAA3','0014000000SQyVGAA1')
 OR Parent.Parent.ParentId IN ('0014000000VqDVWAA3','0014000000SQyVGAA1')
 OR Parent.Parent.Parent.ParentId IN ('0014000000VqDVWAA3','0014000000SQyVGAA1')
 )
 ORDER By Name
]

So the it appears the parser has a hard time dealing with the contradictory inclusion statements. I can create a second set to eliminate the issue.

One last thing - this succeeds:

[
 SELECT Name
 FROM Account
 WHERE Id != '0014000000SQyVGAA1'
 AND Id != null
 AND (
 Id IN ('0014000000SQyVGAA1')
 OR Parent.ParentId IN ('0014000000SQyVGAA1')
 )
 ORDER By Name
]

But this fails:

[
 SELECT Name
 FROM Account
 WHERE Id != '0014000000SQyVGAA1'
 AND Id != null
 AND (
 Id IN ('0014000000SQyVGAA1')
 OR ParentId IN ('0014000000SQyVGAA1')
 OR Parent.ParentId IN ('0014000000SQyVGAA1')
 )
 ORDER By Name
]

So it appears that in order to cause the error, there needs to be both the contradictory statement and at least 2 other inclusion statements within the OR.

Anecdotally, This query runs fine (via the developer consoles query editor) on one of my sandboxes:

SELECT Name, ID
FROM Account
WHERE Id != ''
 AND Id != ''
 AND (
 Id IN ('')
 OR ParentId IN ('')
 OR Parent.ParentId IN ('')
 OR Parent.Parent.ParentId IN ('')
 OR Parent.Parent.Parent.ParentId IN ('')
 )
ORDER By Name

Using static id lists also works fine:

SELECT Name, ID
FROM Account
WHERE Id != '001U000100qh0xJIAQ'
 AND Id != '001U000100qh0xJIAQ'
 AND (
 Id IN ('001U000000ASKzzIAH')
 OR ParentId IN ('001U000000ASKzzIAH')
 OR Parent.ParentId IN ('001U000000ASKzzIAH')
 OR Parent.Parent.ParentId IN ('001U000000ASKzzIAH')
 OR Parent.Parent.Parent.ParentId IN ('001U000000ASKzzIAH')
 )
ORDER By Name

Heres some code I used in the developer consoles execute anonymous code window:

Id someId = '001U000100qh0xJIAQ';
Id someOtherId = '001U000700qh0xJIAQ';

Set<Id> accountIds = new Map<Id, Account>([SELECT Id FROM Account LIMIT 1000]).keySet();

System.debug([
 SELECT Name
 FROM Account
 WHERE Id != :someId
 AND Id != :someOtherId
 AND (
 Id IN :accountIds
 OR ParentId IN :accountIds
 OR Parent.ParentId IN :accountIds
 OR Parent.Parent.ParentId IN :accountIds
 OR Parent.Parent.Parent.ParentId IN :accountIds
 )
 ORDER By Name
]);

Even trying to look for 1000 items in 4 separate clauses I can't repo your error.

Heres the results of running some queries on my org:

SELECT Name
FROM Account
WHERE Id != '0014000000SQyVGAA1'
 AND Id != null
 AND (
 Id IN ('0014000000SQyVGAA1')
 )
ORDER By Name

No Results, but no crash.

 AND Id != null
 AND (

I have no idea why exactly it fails but it seems like adding that 3rd clause to the AND causes the failure. If it was just the ID != '' && Id == '' issue, I'd expect the first one to fail.
