+check=globals
The +check=globals option enables runtime checks to detect corruption of global
variables by introducing and checking "guards" between them, at the time of program
exit. Setting environment variable RTC_ROUTINE_LEVEL_CHECKwill also enable the
check whenever a function compiled with this option returns.
For this purpose, the definition of global is extended to be all variables that have static
storage duration, including file or namespace scope variables, function scope static
variables, and class (or template class) static data members.
