TTree::Process( Proxy ) + AClic: error in dictionary

Dear experts,

I am using ROOT 5.34/09 with g++ 4.8.2 .
I want to run a TSelector-based analysis using the auto-generated proxy with TTree::MakeProxy.

The generated proxy looks fine, and if I run a do-nothing analysis ( the analysis_Process and all other TSelector-like member functions are empty), everything is fine; but if I try to copy-and-paste an already existing analysis inside those functions, I obtain a huge list of errors regarding the dictionary generation that I never encountered before; you can see an example below:

/home/didi/FTKchiara/generatedSel_h_ACLiC_dict.cxx: In function ‘int G__generatedSel_h_ACLiC_dict_3085_0_28(G__value*, const char*, G__param*, int)’:
/home/didi/FTKchiara/generatedSel_h_ACLiC_dict.cxx:793:79: error: ‘class generatedSel’ has no member named ‘operator>>’
const istream& obj = ((generatedSel*) G__getstructoffset())->operator>>((istream) libp->para[0].ref, (G__CINT_IOFLAGS) libp->para[1].ref);
^
/home/didi/FTKchiara/generatedSel_h_ACLiC_dict.cxx:793:115: error: ‘G__CINT_IOFLAGS’ was not declared in this scope
const istream& obj = ((generatedSel*) G__getstructoffset())->operator>>((istream) libp->para[0].ref, (G__CINT_IOFLAGS) libp->para[1].ref);
^
/home/didi/FTKchiara/generatedSel_h_ACLiC_dict.cxx:793:131: error: expected primary-expression before ‘)’ token
const istream& obj = ((generatedSel*) G__getstructoffset())->operator>>((istream) libp->para[0].ref, (G__CINT_IOFLAGS) libp->para[1].ref);

all of these errors are related to the overload of operator>>, operato<< or member G__ateval:

have you ever seen anything like this? do you have any suggestion?
thank you very much in advance.

cheers,
