Surely the above code, which silently discards the exception, 
does not print "hello"?

Regardless, I ran your code with writeln inside the catch(), and 
without the try-catch entirely, with and without nothrow on K's 
destructor. I am unable to replicate the issue on my computer 
with DMD 2.091.0, as well as on run.dlang.io. Is something 
missing in your code here?
