The issue here is that `jl_array_eltype` is already returning a type.
`jl_typeis(v, t)` becomes `jl_typeof(v) == t`, so your checks become:
jl_typeof(array_type) == jl_int64_type
But
jl_typeof(array_type) -> DataType
Instead, either do the equality check directly:
array_type == jl_int64_type
Or use the exported API only (jlapi.c):
strcmp(jl_typename_str(array_type), jl_typename_str(jl_int64_type))
