-// In Release modes, Visual Studio complains that the Operator destructor

-// never returns, which is true by design. 

-// This does *not* depend on llvm_unreachable being dependent on NDEBUG:

-// even if llvm_unreachable is replaced by __assume(false), VC still warns in

-// Release modes but not in Debug modes. The real reason is optimization flags.

-// With /Od in Debug modes the warning is not issued whereas with /O1 it is.

-// I could not find any documentation to this effect, it is reproducable:

-// Try compiling http://msdn.microsoft.com/en-us/library/khwfyc5d(v=vs.90).aspx

-// with /O1 and then with /Od.

-// Anyhow, solution is same as lib/Support/Process.cpp:~self_process().
