Axishandler crashes when releasing Memory
-----------------------------------------
Key: AXISCPP-824
URL: http://issues.apache.org/jira/browse/AXISCPP-824
Project: Axis-C++
Type: Bug
Components: Parser Library - Xerces
Versions: 1.5 Final
Environment: Visual Studio 6.0, Windows 2000, Axis 1.5 and Xerces 2.6
Reporter: Marco Kunze
Priority: Blocker
We developed a Webservice using Axis C++ 1.5.
We tried out the Axis-Nightbuild 1.6 , Xerces 2.2, 2.6 and 2.7.
But the effect was the same when Deleting:
delete (const_cast <char*> (cp_PreviousNameOrValue));
delete cp_CurrentNameOrValue;
The Handler crashes and throws an unknown Exception. We were able to isolate
the error, but the fix from 14.6. doesnt work.
Without freeing the Memory the code works fine. But we have to go productive in
one Month. There is about 20 KB of Data in one Element, so the memoryleak sizes
to a great amount. We tried to find an other workaround, but we were not
successful yet. You did one fix on that method, so we hope you can help us.
Sample Code and an example Soapmessage can be delivered.
void XercesHandler::characters(const XMLCh* const chars,
const unsigned int length)
{
const char* cp_PreviousNameOrValue = NULL;
if( m_pCurrElement && m_pCurrElement->m_pchNameOrValue)
{
if (m_pCurrElement->m_type == CHARACTER_ELEMENT)
cp_PreviousNameOrValue = m_pCurrElement->m_pchNameOrValue;
}
m_pCurrElement = m_pNextElement;
m_pNextElement->m_type = CHARACTER_ELEMENT;
if (cp_PreviousNameOrValue)
{
char* cp_CurrentNameOrValue = XMLString::transcode(chars);
//char* cp_FullNameOrValue = (char*)
malloc(strlen(cp_PreviousNameOrValue) + strlen(cp_CurrentNameOrValue) + 1);
//Chinthana:Removed malloc
char* cp_FullNameOrValue = new
char[strlen(cp_PreviousNameOrValue) + strlen(cp_CurrentNameOrValue) + 1];
cp_FullNameOrValue[0] = '\0';
strcat(cp_FullNameOrValue, cp_PreviousNameOrValue);
strcat(cp_FullNameOrValue, cp_CurrentNameOrValue);
m_pNextElement->m_pchNameOrValue = (const char*)cp_FullNameOrValue;
//free(const_cast <char*> (cp_PreviousNameOrValue));
//free(cp_CurrentNameOrValue);
//Chinthana:Removed free
delete (const_cast <char*> (cp_PreviousNameOrValue));
delete cp_CurrentNameOrValue;
//14/06/2005.............................................................
}
else
m_pNextElement->m_pchNameOrValue = XMLString::transcode(chars);
}
