This code worked in the debugger on my iMac ever since 2019R1 stopping at the second conditional Break statement and finishing to the Return after that if I let it go that far. It hangs now after the latest update, apparently never reaching either of the two conditional “Break” statements. Why is this happening now?

```

Initialize

Var outputCount As UInteger = 0
n = INITIAL_N
bias = INITIAL_BIAS
delta = 0
For Each cp As UInt32 In iri.Codepoints
If (cp > &h10FFFF) Or (cp >= &hD800 And _
cp <= &hD8FF) Then
#If DebugBuild
Break
#Else
Raise New IllegalInputException
#EndIf
Elseif IsBasicCodepoint(cp, False) Then
result = result + Text.FromUnicodeCodepoint(cp)
outputCount = outputCount + 1
End If
Next
handledCount = outputCount
basicCount = outputCount
If basicCount > 0 Then
result = result + Text.FromUnicodeCodepoint(DELIMITER)
End If
While handledCount < iril
m = MaxUInt32
For Each cp As UInt32 In iri.Codepoints

m = cp

#If DebugBuild
