The following code, crashes for some instances of line (as given in the attachment):

std::regex lineExp("tpie::update_fractions\\([ ]*\"([^\"]+)\"[ ]*,[ ]*([^, ]+)[ ]*,[ ]*([^\\) ]+)[ ]*\\);.*", std::regex::extended);
std::string line = <some_long_string_here>
std::smatch matches;
std::regex_match(line, matches, lineExp);


The crash ocure as we are running out of stack space in some possible infinite recurtion. The context of the code can be seen here https://github.com/thomasmoelhave/tpie/blob/cpp11-cleanup/tpie/fractional_progress.cpp#L64
