New possible error with Julia 1.10-beta2

[kbarros]

After upgrading to Julia 1.10-beta2 I am seeing a new error in @report_opt that looks like an avoidable false positive:

using JET

function offsetc(cell::CartesianIndex{3}, ncells, latsize)
    CartesianIndex(mod1.(Tuple(cell) .+ Tuple(ncells), latsize))
end

cell = CartesianIndex(1,2,3)
ncells = (3,2,4)
latsize = (10,11,1)
@report_opt offsetc(cell, ncells, latsize)

Prints:
