Application crash and strange browser Id

[Navi Srob]

Hi. I noticed some program falls when using cefpython. To emphasize the problem I wrote a simple test with nex sequence:

1) Call CreateBrowserSync several times, and print "Test x" after each call

2) wait for 2 seconds, 

3) delete window with browser

4) go to point 1.

With cefpython.LOGSEVERITY_DEFAULT the next output was obtained:

Test 1

[CEF Python] CefBrowser::CreateBrowserSync()

After last string program was quietly terminated (no errors more). The strange thing is  browserId=3809 which already was created. 

cefpython3 v31.2

Would you mind asking on the CEF Support forum about the strange behavior of browser id being reused? Browser identifier is obtained by calling CefBrowser.GetIdentifier(). Looks like an issue in upstream CEF. See http://www.magpcss.org/ceforum/viewforum.php?f=6 . Please provide also information about OS.

Ok, thanks, I will post it on  CEF Support, but first, I need to build same test with 2171 version, may be this already fixed.
