Bug 5857 – std.regex (...){n,m} is bogus when (...) contains repetitions

Uncovered while fixing greediness issues in current implementation. For instance: import std.regex; void main(){ auto c = match("axxxzayyyyyzd",regex("(a.*z){2}d")).captures; assert(c[0] == "axxxzayyyyyzd"); //asserts, there is no match ?! assert(c[1] == "ayyyyyz"); } While it's certainly matches, try http://www.regextester.com/ (both PHP preg & JavaScript one). The reason is that .* on the first iteration jumps out of ...{2} "scope", skipping next iteration of '(a.*z)' before trying 'd'.

Fixed in 2.053 https://github.com/D-Programming-Language/phobos/commit/c3ec6b2387d50ceab14cb648de6abb96b2b11f33
