Subj : Internal compiler error on piece of (simple) C++ code

Hello all,

I am currently in the process of porting a (big) piece of code to BCC551. The
same code compiles & works without problems on various other compilers and 
systems (gcc w/ Linux, FreeBSD, MinGW and Cygwin; MSVC on W32 proper).

When I try to compile one of my .cpp files with BCC551 (or BCB5 or BCB6) I
get an internal compiler error at the end of the function. The function makes
a Xerces-C SAX parser and a memory buffer - the latter of which lives in a
smart pointer class - parses and returns.

The code is inline below. The messages I get are:
Fatal F1004 ..\..\libCMH\CMH_XMLparser-parse.hpp 34: Internal compiler error at 0x45e84a with base 0x400000 in function CMH_XMLparser::parse()
Fatal F1004 ..\..\libCMH\CMH_XMLparser-parse.hpp 34: Internal compiler error  in function CMH_XMLparser::parse()

(in BCB5 and BCB6, I get messages meaning the same thing, but in French)

Here's the code:

bool CMH_XMLparser::parse(void)
{
   TRACE("CMH_XMLparser(0x%.8X)::parse()", (int)this);
   CMH_SAXhandler handler(this);
   SAX2XMLReader * parser = XMLReaderFactory::createXMLReader();
   cmh_autocount_ptr<MemBufInputSource> inputBuffer;

   // FTTB, we don't validate yet
   parser->setFeature(XMLUni::fgSAX2CoreValidation, false);
   // nor do we use name spaces
   parser->setFeature(XMLUni::fgSAX2CoreNameSpaces, false);
   parser->setFeature(XMLUni::fgSAX2CoreNameSpacePrefixes, false);
   // or schemas
   parser->setFeature(XMLUni::fgXercesSchema, false);
   parser->setFeature(XMLUni::fgXercesSchemaFullChecking, false);

   // set the handlers
   parser->setContentHandler(&handler);
   parser->setErrorHandler(&handler);
   inputBuffer = new MemBufInputSource( (const XMLByte*)theXMLdocumentContents.c_str(), theXMLdocumentContents.length(), fake_sysID, false );
   parser->parse(*inputBuffer);

   return(handler.num_errors() == 0);
}

The function is part of a class but lives in its own file 
(CMH_XMLparser-parse.hpp, included by CMH_XMLparser.cpp). Other than being 
included by the CPP file, it also contains an include directive of its own:
#include "CMH_SAXhandler.h"

My questions are:
* is there any way to nail down the error to, say, the preprocessor, the 
  assembler, the compiler itself, ... ?
* is there anything really supicious in the code or in the setting (code in
  separate file) that BCC might not be able to handle?
* is there any way to get the compiler (driver) to save any intermediate files
  (as with gcc -save-temps)?

Any suggestions, pointers and solutions(!) would be very welcome.

Thanks,
