I’m always getting an exception when trying to escape a backslash like this:
boost::regex shaderRegex{ "test\\" };
Am I doing something wrong?

A literal backslash would be
boost::regex shaderRegex{ "test\\\\" };
In a C++ string, the characters \\ represent a single backslash character.
To represent a regex literal (escaped) backslash, you would need two of those.
If this looks confusing, you can also use a C++11 raw string literal.
boost::regex shaderRegex{ R"(test\\)" };
