after upgrading to CEF 2623 we are experiencing a crash of the renderer process. The repro is as follows:
- launch our application
- resize the window containing the CEF control multiple times
- shutdown
The crash has the following stack trace:

After looking at the disassembly of the locations on the stack, we can see that the allocated size is ~5MB, while the memory used by the process is around 150 MB. No way is this a "real" out of memory error. We are running our 32 bit application on a 64bit Windows 8.1 machine. We are not compiling CEF manually.
Any ideas ?

But still - the crash doesn't reproduce.
