The extra code that scans for duplicates and throws an exception was added via I95dea67 in 2017. I'm not entrirely sure why. This should be impossible in all relevant real-world scenarios. Maybe it happened in a local dev scenario? Even if, duplicates are harmless. Let me explain: The only way a duplicate can end here is when the same magic word is added twice to the $this->names array. The only thing that happens then is that the resulting regex contains one of the sub-patterns twice. It doesn't matter which one matches. We know these subpatterns are identical. Unfortunately the PCRE compiler doesn't know and assumes duplicate names are a problem. We have two options to fix this: Strip duplicates in $this->names with array_unique() or tell the PCRE compiler that duplicates are ok with the /J modifier. I would like to avoid the extra, potentially expensive array_unique() because, as said, duplicates never happen in real-world scenarios. The /J modifier is supported since PHP 7.2.
