**well-defined undefined behavior**; rants in a spec.

I know that every math textbook possibly for every year of school 
disagrees with 1/0==int.max(possibly those math text books out 
number humans); and compilers are very very very clever detecting 
when they can change how your code works obeying such a spec with 
1000000 lines of code in llvm to enable what c++ does and this 
takes an hour of computer to handle these massive projects. and 
theres the cve database, theres the iso standards there nist, 
ieee float spec and blah de blah

There was a 50 step process that created the last memory exploit 
with hyper autists quoting formal texts for why they were right 
to let it happen.

So much to know, such big words, all tabulated and organized.

Its called "undefined behavior" yet its in these books, we can 
all just look at the results, theres plenty of learning resources 
about each, theres rants on forums on each little elemental 
design flaw and why its a "impossible to fix" problem.

The unknowable behavior is running 1000000 lines of code written 
by 10000 people, and thats the cause of the ransom ware. It 
wasn't the so called "undefined behavior" of being lazy and 
missing a bounds check, each step of the long process is quite 
aware people miss bound checks and we all have direct experience 
with segfaults.

Its impossible to comprehend the ever growing machine, but you 
can simply have the arrogance to say its wrong and just do 
things. We are defining things all the time, make new elemental 
pieces to solve problems even if people say they are hard and 
require the big pile of complexity or cite the big pile of 
complexity inability to solve it.

ez as `1/0==int.max`, yes, I know what a math book would say and 
have seen a calculator. Cut the Gordian knot.
