[input_server] crash in atomic_set

[Sarek01]

Running haiku hrev54154+97, which was updated with software updater approximately 24 hours ago. Update proceeded with no issues and haiku worked normally until normal shutdown. Upon startup this evening, startup proceeded through the boot screen up until the Tracker background appeared, then it dropped straight into KernelDebuggerLand. I was unfortunately not able to get a shot of the screen, i do however have the syslog. According to said syslog, it appears that the VM had a segment violation. Log snippet attached.

This is not a KDL, it is actually an input_server crash, which also has a white screen as it goes to a Debugger prompt.

If it still occurs, please type "save-report", and this should write a report to your Desktop that you can then upload here with more information.

Actually this is a duplicate of #12412.
