File android_webview/browser/scoped_app_gl_state_restore.cc (right):

https://codereview.chromium.org/288003002/diff/1/android_webview/browser/scop...
android_webview/browser/scoped_app_gl_state_restore.cc:154: << "Incoming GLError
" << error;
Since it's an error stack you need to loop over it, see
ErrorStateImpl::ClearRealGLErrors() in error_state.cc

Huh, didn't know it was a stack. While loop it is then.
