UnicodeMatchPropertyValue assertion fails by UnicodePropertyValueExpression

[Jack-Works]

For the RegExp: /[\p{Hex}]/u:

CompileToCharSet
For production UnicodePropertyValueExpression :: LoneUnicodePropertyNameOrValue, s is Hex, in step 2, it calls UnicodeMatchPropertyValue(General_Category, s)

UnicodeMatchPropertyValue
2. Assert: v (in this case, Hex) is a property value or property value alias for the Unicode property p (in this case, General_Category) listed in PropertyValueAliases.txt.

In PropertyValueAliases.txt, no entry starts with gc ; Hex, so this assert should fail.
