CEF ceflib.dll appcrash

[carlitosbg]

Hello everyone

Since 2 weeks ago I started to using the CEF library into a project which I use maps with.
The map functions works fine, I show the map on a separated window in which the CEF browser is initialized correctly.
However sometimes when I close the window which contains the map, I get an appcrash error message, please check the image I attached to this post (CEF_appcrash.png)

I have searched about this over all internet, CEF forums, blogs, but I haven't found a solution for this.
I am initializing the CEF project properly:

Code: Select all


 Dim settings As New CefSettings
#If DEBUG Then
            settings.CefCommandLineArgs.Add("renderer-startup-dialog", "1") 'in order to attach the process of CefBrowser and get an more detailed stack error message (libcef.dll appcrash problem).
#End If

            If Not CefSharp.Cef.IsInitialized Then
                CefSharp.Cef.Initialize(settings)
            End If



And as I said, sometimes works very good (I close the window containing the map and it does not crash) but suddenly when I close that window by the fifth or sixth time then
I get the appcrash error message with exception code "c0000005"

Please help me with this, another additional info I get on the Debug.log file on my output folder is this:

Looks like you have a debugging issue, see https://www.google.com/search?q=vshost3 ... &gws_rd=cr

I checked your answer and then when the crash happens, I get this error message on a message box:

"Unhandled exception at libcef.dll in app.exe: 0xC0000005: Access violation reading location 0x00000000."

I guess the problem could be to some kind of bug on the assembly libcef.dll, but I have no idea how to solve it.

Is there a new release of libcef.dll which I can use??

[carlitosbg]

I used the Release symbols of libcef.dll (libcef.dll.pdb, 32 bits) and this is the message I get, please see image

After that I press "Break Button" and it seems the symbol is loaded well, but then I get a weird message, please see the second image

Now I read that is possible to build the CEF project but I don't know where I can download the entire source code.

Please help me, thanks in advance.

Copy the whole stack trace and paste it here as code.

[carlitosbg]

I followed the steps described on this link:

https://github.com/cefsharp/CefSharp/issues/1683

And now I get no error messages by opening the maps more than one time, it seems is working now but anyway I will do more testing just to be sure.

Anyway here I give you the full stack trace

These are some logs, not stack trace. In one of your screens the window titled "Call Stack" is the stack trace in question.
