CPD warning with version 0.9.8

[ghost]

I have updated my SonarQube 6.2 with the version 0.9.8 of the cxx plugin. The plugin produces now a lot of traces during the analysis:

INFO: Sensor c++ SquidSensor
INFO: SonarQube 6.2 or newer environment
WARN: CPD error in file '/home/phil/.../Provider.cc' at line:395, column:47
...

Those warnings where not produced with the version 0.9.7 of the plugin.

It seems that this warning is produced only when C++ string constants are defined on multiple lines. Examples of two cases which produces this warning:

sql << "SELECT epsg_datum.datum_name, \
               epsg_datum.datum_code  \
                    FROM epsg_datum";
throw MyException("hello "
                  "world");

@phcouton this was also in old versions an issue. Problem is that preprocessor is merging/changing the code and resulting line numbers do no more fit to original source file. I see no way to solve this.
