    Description

      Calling NtContinue with bogus MxCsr value can hang the system, when compiled with KDBG=1.

      To test: comment out `stmxcsr [rcx + JbMxCsr]` in setjmp and run ntdll_apitest:exception. Configure with `-DKDBG=1 -D_WINKD=0`.

      TODO:

      Validate user mode context in KiSetTrapContext. Potentially integrate KiSetTrapContext into KeContextToTrapFrame.
