The following parses fine for me with swig-4.2.1:

%module example

%inline %{
#include <regex>
#include <string>
std::string _endHeaderString;
std::regex endheader{R"([ \t]*)" + _endHeaderString + R"([ \t]*)"};
%}

If you are still having problems, please raise a Github issue with all the
details to replicate.
