Somewhat reduced test case:
void main(){
    import std.regex;
    auto r = regex(`([а-яА-Я\-_]+\s*)+(?<=[\s\.,\^])`);
    match("аллея Театральная", r);
}

Investigation shows it's related to lookaround.

P.S. I suggest in future to post new bugs as new reports, even if the symptoms
are similar to some older bug. REOPENED is for cases where the same issue
happens again (regression, patch was reverted etc.).
