#1920: when considering a block starting by "while 0", the compiler optimized the whole construct away, even when an 'else' clause is present:: while 0: print("no") else: print("yes") did not generate any code at all. Now the compiler emits the 'else' block, like it already does for 'if' statements. Backport of r60265.
