CefClient.exe crash in libcef.dll ~LogMessage()

[smisro]

Hi,
I'm using 'cef_binary_3.3538.1849.g458cc98' and built the solution with /MD option. I Used the following to do that:

C:\work\cef-project\build>CMake -G "Visual Studio 14 Win64" -DCEF_RUNTIME_LIBRARY_FLAG=/MD -DUSE_SANDBOX=Off ..

All projects in the cef.sln compile and build fine.
When I launch cefclient.exe in debug mode from visual studio, it launches with the default url pointing to "http://www.google.com" and within a few seconds after loading, the application throws an exception with the following callstack. If I change the default URL to something else ( say http://www.yahoo.com it doesn't crash ).

Any suggestions on how to fix this?

Thanks

What OS are you running on? Does it crash if you make a clean build without CEF_RUNTIME_LIBRARY_FLAG?

[smisro]

I'm on Win 10 - 1709. I just tested without the "CEF_RUNTIME_LIBRARY_FLAG" (so the build config is now /MTd by default) and see the same issue.

Btw, I found someone else reporting a similar callstack here : viewtopic.php?f=6&t=13977
The suggested solution doesn't help here. Ignoring the exception and continuing doesn't continue execution. It crashes at this point.

That link seems relevant. By “ignore” it means use a Release build of libcef because the failure is a Debug check.
