rootcint problem

Hello All,

I've run into a problem with ROOT 4.00.08 being used with GCC 3.3.6 in a corner case of the handling of templates. I'm sorry, but I haven't checked in later versions.

The problem seems to originate from how ROOTCINT handles sub-classes defined inside of a template. I've attached a short example.

In the example, the CINT dictionary was generated using:

rootcint -f THandle_Dict.cxx -c -p THandle.hxx THandle_LinkDef.h

The problematic line is in THandle_Dict.cxx:

static int G__THandle_Dict_143_2_0(G__value *result7,G__CONST char *funcname,struct G__param *libp,int hash) {

   G__letint(result7,85,(long)((const THandle<TObject>*)(G__getstructoffset()))->operator Tester*());    return(1 || funcname || hash || result7 || libp) ; }

I believe the correct code is:

static int G__THandle_Dict_143_2_0(G__value *result7,G__CONST char *funcname,struct G__param *libp,int hash) {

   G__letint(result7,85,(long)((const THandle<TObject>*)(G__getstructoffset()))->operator THandle<TObject>::Tester*());    return(1 || funcname || hash || result7 || libp) ; }

Thanks,
Clark
