parser error during marco resolving

[schroeca-zz]

I'm using your plug-in to parse SystemC source code. Which is fully compliant to the C++ standard.

The following source code leads to an parser error.

First file:

SC_METHOD(sc_method1);

The SystemC macro SC_METHD is defined in sc_modules.h which looks like this:

#define declare_method_process(handle, name, host_tag, func)        \
    {                                                           \
        ::sc_core::sc_process_handle handle =                      \
        sc_core::sc_get_curr_simcontext()->create_method_process( \
        name,  false, SC_MAKE_FUNC_PTR( host_tag, func ), \
        this, 0 ); \
        this->sensitive << handle;                                        \
        this->sensitive_pos << handle;                                    \
        this->sensitive_neg << handle;                                    \
    }

#define SC_METHOD(func)                                                       \
    declare_method_process( func ## _handle,                                  \
                            #func,                                            \
                            SC_CURRENT_USER_MODULE,                           \
                            func )

If I paste the resolved macro directly in my source file, everything works fine.
If I use the SC_METHOD macro i get an error.

My SonarQube version is: 4.5.6
My Plubin version is: 0.9.4

Please use the sslr toolkit to reduce the problem/example: https://github.com/SonarOpenCommunity/sonar-cxx/releases/download/cxx-0.9.4/sslr-cxx-toolkit-0.9.4.jar

Remove all parts not needed to reproduce it, e.g.:

#define declare_method_process(handle, name, func)        \
    {                                                           \
        int handle = f(name, SC_MAKE_FUNC_PTR(func)); \
    }

#define SC_METHOD(func)                                                       \
    declare_method_process( func ## _handle,                                  \
                            #func,                                            \
                            func )

I'm very sorry but I'm not a SonarQube Admin and it is not possible to remove anything from the define statements.

I'm also not sure how to use this sslr toolkit.

I tried to reproduce the behaviour with different modifications of the define statements.

It seems that the **"::"**sc_core:: ... which is necessary to be sure that it is referenced to the global namespace causes the parser crash

This seems to be related to #526

reproducible with this:

#define SC_METHOD(func) declare_method_process( func ## _handle, #func, func )
SC_METHOD(test);

Problem is the #func after func ## _handle.
