Fixes #46844
The macros introduced with #46739 had a bug. Because I was on autopilot and used
do{...} while(0)
in the macros, it introduced a new scope and the ShutdownGuard class would not be held for the duration of the call. I did test it, since it prevented new calls from entering the profiler code it drastically reduced the hit rate but there still was a race condition.
