You are allowed to use it in exceptional circumstances.  Not normally
"I see no reason to go forward" but "I can not go forward because some
critical operation has failed."  There is also internal_error for,
well, internal errors; use that for data corruption.  And gcc_assert
and gcc_unreachable for things that can not happen.
