not sure why in C backend it compiles,

as I found no / for int64, there seems to be only int/int in system.

It compiles in C backend because, at least in x64 the operators of / is converted to int first, a.k.a. that's rewriten roughly as:

echo int(1.int64) / int(2.int64)

donno what will happened on 32 bit machine. 🤔
