[Bug c++/42810] Enumeration with sequential values has its for-loop exit condition optimized out.



------- Comment #6 from tony3 at GarlandConsulting dot us  2010-01-19 23:05 -------
There is a related bug here:

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=36170

But unlike that bug which uses an out-of-range enum value, this case does not.
We are testing  'value <= max_valid_enum_value'.  So I've entered this as a
different bug for reconsideration about how the compiler is handling valid
enumeration values in -O2.
