for 1 of 2 union split cases, non-boolean (Missing) used in boolean context

[dpinol]

I haven't been able to create a minimal test case. This is my environment

• Julia 1.7.2
• JET 0.5.7
• Running report_package on my package A reports no issues
• Running report_package on a package B which uses A reports an issue on a function on package A
• Running report_call or @report_call on the failing function I get no error.

This is the relevant code

const TrackFieldValue = Pair{String, String}
const TrackFieldsType = AbstractVector{TrackFieldValue}

struct PerformanceTracker
    tags::TrackFieldsType
end
# the line below reports the issue
function track(r::PerformanceTracker)
 @info "Tracking performance for tags $(r.tags):"
end

Adding skipmissing does not help
@info "Tracking performance for tags $(skipmissing(r.tags)):"

Strangely, none of the following lines trigger the report

    println(r.tags)
    println(join(r.tags, ","))
    println(join(string.(r.tags), ","))

Any idea on what's the isssue?

thanks

It seems like I can't reproduce this error at least on the JET master.
