It is a programming error because the underlying code cannot handle it. If, 
from the beginning of
time, double free would have been handled properly then we wouldn't have 
thought twice about it.

You want to catch double frees. What if double frees are no-ops?

I do not see how a double free can result in _logical_wrong_behaviour_ of the 
program and the
program keeps on running (like an incoming packet being dropped because of 
double free). Double
free will _only_and_only_ result in system crash that can be solved by setting 
'x' to NULL.
