I think the error is in parsers/SAXParser.cpp:
SAXParser::parse(const char *const systemId, const bool reuseGrammar):
fScanner->scanDocument(systemId, reuseGrammar);
This calls
void XMLScanner::scanDocument( const XMLCh* const systemId
, const bool reuseGrammar)
you send const char *const systemId as a const XMLCh *const systemId.
XMLCh is, when I understand rightfully, a wchar_t. In XMLScanner::scanDocument
a XMLURL object is created with this const XMLCh* const, which is in deed
a const char *const. The XMLURL-Constructor
XMLURL::XMLURL(const XMLCh* const urlText)
is called, which calls
void XMLURL::setURL(const XMLCh* const urlText)
This Method calls
void XMLURL::parse(const XMLCh* const urlText)
This Method makes a pointer 'XMLCh *srcPtr' to urlText and calls (in a
loop):
XMLPlatformUtils::fgTransService->isSpace(*srcPtr)
This Method is defined in IconvFBSDTransService.cpp. It expects a XMLCh (which
seems to be a wchar_t) and runs
mbstowcs( (wchar_t*) &toCheck, buf, 1 );
on *srcPtr, wich is really a const char. Could this be the error?

Thanks.

So, I did it ;-) it's your turn ;-)
