Segmentation fault when the length of parsing filename > 130 characters
-----------------------------------------------------------------------
Key: XERCESC-1688
URL: https://issues.apache.org/jira/browse/XERCESC-1688
Project: Xerces-C++
Issue Type: Bug
Components: DOM
Affects Versions: 2.5.0
Environment: linux kernel 2.4
Reporter: xiangzhu K
Priority: Critical
#include <xercesc/util/PlatformUtils.hpp>
#include <xercesc/dom/DOMNode.hpp>
Some source code as
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
#include <xercesc/dom/DOMDocument.hpp>
#include <xercesc/parsers/XercesDOMParser.hpp>
#include <xercesc/util/XMLUni.hpp>
#include <xercesc/util/XMLString.hpp>
#include <xercesc/framework/StdOutFormatTarget.hpp>
#include <xercesc/util/XercesDefs.hpp>
#include <xercesc/sax/ErrorHandler.hpp>
...
parser = new XercesDOMParser;
...
SetDOMParser::internal_parse(filename)
{
...
parser->parse(filename);
...
}
...
int main(int argc, const char *argv[])
...
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
*filename* is transfer by parameter argv[].
Built and run the program. Inputing command format like:
setParse [filename]
When input the filename whose length is longer than 130 chars, like
---------------------------------------
setParse
a01234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567891
---------------------------------------
program will cast "Segmentation faul" error and break.
Why???? Who can help me?
I used gdb to debug. Followed is some backtrace info:
