255 < 10 is true

[jarcen]

Simple code to reproduce:

if(255 < 10){
    write_char('1');
}
else {
    write_char('0');
}

This outputs 1.

Changing 255 to 254 outputs 0 as expected.

This was checked in multiple online interpreters.

it is not a bug from the compiler, the interpreters only support 8 bit numbers. try https://copy.sh/brainfuck/, you can change the cell size and it will work as intended.

I think c2bf aims to work with interpreter where integers are 8bits, so I would consider this a bug.

That said, I haven't looked at that project for 12 years, so this is unlikely to get fixed.
