Rubberduck: Resolver Error Build 2.0.9.18871

[halcwb]

When I try to refresh Rubberduck, it runs into a Resolver Error. I have attached the log file.

P.s. Might I suggest that you log the Rubberduck version and Office info? Would make it much easier to point the problem to specific versions.

Re PS: That was already incorporated. The newest version will log basic OS and Host information when starting up.

The Log you have there is pretty interesting. @retailcoder The SafeComWrapper.Release results in an ArgumentException as soon as it goes into Item:

The error described in the log that can be observed is the following:

@halcwb Somewhere in your code you use const and the parser doesn't like that. this should manifest as a parser error (but doesn't for whatever reason). Have you double-checked your code compiles without problems in the vbe?

Note that the log shows Rubberduck was trying to shut down in the middle of parsing 😕

[halcwb]

The code compiles without problems. I use Option Explicit.

I use const as a prefix for private const variables. I use CONST_ prefix for public const variables. I do not have an instance of const as whole word in my code. So, I don't think that Rubberduck should fail because of this.

P.s. Feel free to check out my repository at: https://github.com/halcwb/AfsprakenProgramma

[comintern]

The prefixes aren't the issue - this resolves just fine:

Public Const CONST_Foo = 42

Sub Bar()
    Debug.Print CONST_Foo
End Sub

What _isn't_ clear is why there's still a parser thread running at that point in the log. The inspections finish and the Find command starts here:

2016-12-19 15:28:44.4846;DEBUG;Rubberduck.UI.Command.MenuItems.ParentMenus.ParentMenuItemBase;(2126321) Executing click handler for menu item '&Find all references...', hash code 26250893;
2016-12-19 15:28:53.3776;TRACE;Rubberduck.UI.Inspections.InspectionResultsViewModel+d__38;Inspections loaded in 39072ms;

Then shortly after, the Settings click handler starts:

2016-12-19 15:29:54.9796;DEBUG;Rubberduck.UI.Command.MenuItems.ParentMenus.ParentMenuItemBase;(19136893) Executing click handler for menu item 'S&ettings', hash code 36712608;

But...there isn't any parser state changed logged before it hits the parser error here:

2016-12-19 19:00:20.1276;ERROR;Rubberduck.Parsing.VBA.RubberduckParser;Exception thrown acquiring declarations for 'frmNaamGeven' (thread 17).;System.NullReferenceException: Object reference not set to an instance of an object.

at Rubberduck.Parsing.VBA.RubberduckParser.ResolveDeclarations(IVBComponent component, IParseTree tree) in c:\Users\Mathieu\Documents\GitHub\Rubberduck\Rubberduck.Parsing\VBA\RubberduckParser.cs:line 549

My suspicion is that this is related to issues in tracking the parser state. Possibly another manifestation of the underlying cause for #2459?

[retailcoder]

@comintern that looks very very much like the COM wrapper iterator bug causing an NRE when iterating form controls - that one is fixed already. ...I'll sync up [next] tonight and see if 2.0.10 can be released as is - seems a lot of 2.0.9 bugs are off the table already.

This bug was resolved in build 2.0.10.36196.
