Folks,
I am trying to track down a strange application segfault error 15 bug - which is resisting any attempts to be explained by an application bug.
Hypothetically, if for some reason - the KPTI code failed to switch to the user CR3 while returning back, the kernel would presumably kill the application in the first instruction that it executed in user-space. In this case, would there be any other helpful messages in the kernel syslog other than segfault error 15, or is a completely different error message dumped ?
