Description
The code below that is supposed to replace matches of a regex crashes with Thread 1: EXC_BREAKPOINT (code=1, subcode=0x2676b2ff8) (also with e.g. just "(text)" as input).
Reproduction
print("text".replacing(/([^a-zA-Z]|^)(text)(?=([^a-zA-Z]|$))/) { match in
"\(match.output.1) \(match.output.2) "
})Stack dump
