problem with regex

Hi -- I'm using the regex classes to perform syntax highlighting of 
source code similar to the provided "snip4" sample (included in the 
regexx documentation).  I'm building on VC6.

The problem I have is actually evident in the snip4 sample itself.  
The code will seemingly go into an endless loop inside the 
function "query_match_aux()", which is intenarlly called by 
the "regex_merge()" function.  

The data I am passing is simply a nasty (long) preprocessor 
declaration:

#define IMPLEMENT_SERIAL_COM(class_name, base_class_name, wSchema) \
        CObject* PASCAL class_name::CreateObject() \
        {	class_name *pOb = new class_name; \
                pOb->_m_bAlreadyLoaded = FALSE; \
                return pOb; } \
        _IMPLEMENT_RUNTIMECLASS(class_name, base_class_name, wSchema, 
class_name::CreateObject) \
        AFX_CLASSINIT _init_##class_name(RUNTIME_CLASS(class_name)); \
        CArchive& AFXAPI operator>>(CArchive& ar, class_name* &pOb) \
        {	pOb = (class_name*) ar.ReadObject(RUNTIME_CLASS
(class_name)); \
                if (pOb != NULL) \
                        if (pOb->_m_bAlreadyLoaded) \
                                pOb->ExternalAddRef(); \
                        else \
                                pOb->_m_bAlreadyLoaded = TRUE; \
        return ar; }

To reproduce the problem, simply save the above text as a file and 
pass it to a compiled snip4 example.  

I'd appreciate any help or input -- debugging in regex isn't fun 
since I don't know what everything does!  Thanks,
