inconsistent report of "runtime dispatch detected: Base.InexactError"

[dpinol]

Hi,
the following code

using JET
mutable struct MutStruct
    value::Float64
end
const ms = MutStruct(3.4)
function rc()
     period = trunc(Int, ms.value)
     @debug "cd" cd = ms.value
end
@report_opt rc()

reports

┌ @ float.jl:812 Base.InexactError(:Int64, Int64, %4)
│ runtime dispatch detected: Base.InexactError(:Int64::Symbol, Int64, %4::Float64)

Shouldn't Julia be able to invoke the concrete trunc version for Float64? invoke(trunc, Tuple{Float64}, ms.value) doesn't report the dispatch, but it's not feasible for me because I need the conversion to Int. . So I tried 'invoke(trunc, Tuple{Type{Int}, Float64}, Int, ms.value)', but it also reports dispatch. Finally I found that unsafe_trunc(Int, ms.value) also avoid the dispatch report. Do you know if there's a better way? thanks

The following alterations to the code also avoid reporting the issue. I thought that it was caused due to the code being inlined, but adding @noinline also avoided the dispatch report.

• Declaring the struct non mutable
• Commenting out the @debug line
• Changing the @debug line with @debug "cd" cd = 3.2

thanks

The runtime dispatch error seems to come from the line @debug ..., which is very expected.
