If a regular expression contains more than 99 subexpressions that need to be matched and replaced (if matched), then it cannot be currently handled with the boost::regex_replace function because the format string cannot refer to a subexpression with an index greater than 99. Is this current limitation necessary? If so, why?" Feature Requests closed Boost 1.38.0 regex Boost 1.36.0 Problem fixed
