Crash in SAX2XMLReader::loadGrammar() (Xerces 2.8.0)
Hi,
I am using an older version of xerces (2.8.0) and. sometimes, get a crash in
SAX2XMLReader::loadGrammar(). A stack trace of the crash is attached. Please
suggest if this has been fixed in the latest version or any other patch?

Hi,
I am parsing a VXML document (another open source vxml engine, OpenVXI, is
being used for this). The value of the first argument to
SAX2XMLReader::loadGrammar() is "http://www.w3.org/TR/voicexml21/vxml.xsd".
I am not sure how this works but is an http URI a valid path name for this
API?
Regards,
Anshuman

Anshuman,
Can you confirm that there is not a problem with the markup in the DOCTYPE
section of your XML document?
Sincerely,
