How to log freezes

I have installed VS, compiled debug version and been using it under debugger.

When I paused program I was at PowerEditor\src\Misc\PluginsManager\PluginsManager.h on line:

    void notify(SCNotification *notification) {
        for (size_t i = 0 ; i < _pluginInfos.size() ; i++)
        {
            // To avoid the plugin change the data in SCNotification
            // Each notification to pass to a plugin is a copy of SCNotification instance
            SCNotification scNotif = *notification;
------>            _pluginInfos[i]->_pBeNotified(&scNotif);
        }
    };

scNotif structure was:

    scNotif    {nmhdr={...} position=881516 ch=4652412 ...}    SCNotification
        nmhdr    {hwndFrom=0x000808ca idFrom=154584280 code=1008 }    NotifyHeader
        position    881516    int
        ch    4652412    int
        modifiers    883412    int
        modificationType    -86547003    int
        text    0x000d7408 "`t
"    const char *
        length    4657716    int
        linesAdded    -1    int
        message    881544    int
        wParam    4652412    unsigned long
        lParam    883440    long
        line    -86547167    int
        foldLevelNow    -86561999    int
        foldLevelPrev    4657716    int
        margin    883456    int
        listType    -86547151    int
        x    -86562047    int
        y    4657716    int
        token    940636    int
        annotationLinesAdded    14352488    int

and when I stepped once I went into ChangeMarker code:

>    NppPlugin_ChangeMarker.dll!61703593()    
     [Frames below may be incorrect and/or missing, no symbols loaded for NppPlugin_ChangeMarker.dll]   
     NppPlugin_ChangeMarker.dll!61704fed()    
     NppPlugin_ChangeMarker.dll!6170144a()    
     notepadPlus_Debug.exe!PluginsManager::notify(SCNotification * notification=0x000d3d34)  Line 105 + 0x1a bytes    C++

     notepadPlus_Debug.exe!Notepad_plus::fileSave(Buffer * id=0x00000000)  Line 1186 + 0x1a bytes    C++
     notepadPlus_Debug.exe!Notepad_plus::command(int id=41006)  Line 3145    C++
     notepadPlus_Debug.exe!Notepad_plus::runProc(HWND__ * hwnd=0x000808ca, unsigned int Message=273, unsigned int wParam=41006, long lParam=0)  Line 7804    C++
     notepadPlus_Debug.exe!Notepad_plus::Notepad_plus_Proc(HWND__ * hwnd=0x000808ca, unsigned int Message=273, unsigned int wParam=41006, long lParam=0)  Line 9119    C++

Of course I paused debugger Npp when freeze happened.

It can happen with almost every file. Last time it was file about 300 lines long.

Can be related to long sessions but I'm not sure if "extremely long" is good word. Maybe half an hour or a bit more of editing. Even more likely it's related as it happens after some editing and not immediately after opening file.

I can't reproduce it on demand unfortunately.

I don't know NPP internals but that scNotify structure looks a bit weird to me:
position 881516 int
length 4657716 int

Quite a big values. Not sure what they mean but file was not big at all (about 5kB).

I cant reproduce the error, but it happens two or three times a day. It's exactly as I said, I open a file and the markers are all yellow, if I press any key, NPP crash. But I can close if I dont press any key, and try to reopen the file, but take two o three tries to get ir right.
Sometimes I open another file, and the reopen the "bad file", to get it right.
If you tell how can I debug it, or something, I can help you.
By the way, I use Windows 7 64bits, but in Vista 64 I had the same problem.

Rafał,
Two things.  One can you reproduce well enough to provide the steps, and a file?

If not, would you be willing to DL the source of nppiface lib and build/use a debug version of that?

I'm really curious as to what the scn looks like that is getting processed within the CM code during the save routine.

Thanks again.

An update...

Rafał has joined us in #notepad++ on Freenode and has setup to run N++ with the ChangeMarker plugin in debug mode.  If it happens again he should be able to see what's going on.

Hi again! Ive been away. Today it happened again, I can send you the file, but I dont think the problem is the file.
How can I install de marker in debug mode? I use npp ALL LONG DAY, so I can be useful.
By the way, I dont use FTPSync, I used to, but no now.

Thanks!
