Only one way it happens..and it's part of the program.
one can say it was NOT deliberate.
How many others are using the same program.
Where did the program come from? Arrest them!!
I too have programming experience and I agree with you 100%. It had to be deliberate and the version of source code used to compile the executable binary can be backtracked to. There are also reverse compilers if they were really good at covering their tracks. This is not a hardware issue. If it was it would be isolated to one machine and there is a 99.999% cancer that a harrdware error would be catastrophic and shut down he machine.
This is malicious code meant to switch a smaller but signifcant enough votes to tip the election but still allow some votes for Trump.
