A raised exception redirects the target thread to a stub that runs the handler and returns through RtlRestoreContext. On Windows 10 (19045) RtlRestoreContext restores in user mode only when the context flags are exactly CONTEXT_FULL | CONTEXT_SEGMENTS (CONTEXT_XSTATE aside); for the CONTEXT_FULL | CONTEXT_FLOATING_POINT context it was given, it calls NtContinue. When the next raise suspended the thread inside that system call, NtContinue then replaced the redirected context with the one it was restoring, so the handler never ran although sceKernelRaiseException had returned 0. guest_raise_exception lost such a delivery to its busy thread in about one run in five and hung until the ctest timeout. The context is now read with CONTEXT_SEGMENTS, so the handler returns through the user-mode restore, and a raise that finds the thread inside NtContinue or NtContinueEx (an APC or an exception handler returning) resumes it and suspends it again.
