Pointer Integer addition ignored when in a function. #60009
Description
Starting in Julia 1.12, when adding a pointer to an integer in a function, the addition is ignored. When I do the addition outside the function, it works as expected.
function null_offset(offset)
Ptr{UInt8}(C_NULL) + offset
end
@show Ptr{UInt8}(C_NULL) + Int(100)
@show null_offset(Int(100))Ptr{UInt8}(C_NULL) + Int(100) = Ptr{UInt8}(0x0000000000000064)
null_offset(Int(100)) = Ptr{UInt8}(0x0000000000000000)
