[jira] Created: (XERCESC-1241) XMLFormatter attempts to deallocate unallocated memory
Message:
A new issue has been created in JIRA.

http://issues.apache.org/jira/browse/XERCESC-1241
Here is an overview of the issue:
---------------------------------------------------------------------
Key: XERCESC-1241
Summary: XMLFormatter attempts to deallocate unallocated memory
Type: Bug
Status: Unassigned
Priority: Major
Project: Xerces-C++
Components:
Utilities
Versions:
2.5.0
Assignee:
Reporter: D. North
Created: Thu, 8 Jul 2004 12:57 PM
Updated: Thu, 8 Jul 2004 12:57 PM
Environment: Not needed
Description:
In line 399 of framework/XMLFormatter.cpp, there is the statement:
fMemoryManager->deallocate(fAposRef); //delete [] fAposRef;
Unfortunately, in order for this to succeed without sigsegv'ng, fAposRef must be non-null, which is [apparently] possible only if the right stuff has been passed into a call to XMLFormatter::formatBuf(...
Reference XERCESC-71 for a related change in this area.
I can provide sample code that demonstrates the failure if needed.
Regards.
David.

The following comment has been added to this issue:
Author: David Bertoni
Created: Thu, 8 Jul 2004 1:52 PM
Body:
The bug is in your code. You are terminating Xerces-C before all Xerces-C objects are destroyed. Try the following:
int main(int argC, char* argV[])
{
XMLPlatformUtils::Initialize();
{
SAX2XMLReader* parser = XMLReaderFactory::createXMLReader();
fudHandlers handler(encodingName, unRepFlags, expandNamespaces);
parser->setContentHandler(&handler);
XERCES_STD_QUALIFIER cerr << "Nuking parser...\n";
delete parser;
}
XMLPlatformUtils::Terminate();
return 0;
}

Ok... Thanks [he said, sneaking into hiding behind the nearest large tree]....
I'm _really_ new to C++, and it is very clear I have missed something really important here... I'll now go figure out the difference.
Very sorry for the interruption ... please close ticket.
Thanks again!

The deallocate() method should handle a NULL argument; can you attach the code showing the crash?

The following comment has been added to this issue:
Author: David Bertoni
Created: Thu, 8 Jul 2004 3:34 PM
Body:
Please don't use a bug report to ask questions -- use the Xerces-C mailing list.
You still some bugs with your code. You are creating a Xerces-C object before initializing the library:
SAX2XMLReader* parser = XMLReaderFactory::createXMLReader();
fudHandlers *handler;
XMLPlatformUtils::Initialize();
The the compiler error is a result of using private derivation from XMLFormatTarget. You will not be able to do this if you want to use new with your class.
Note also that this line is incorrect:
parser->setContentHandler(&handler);
In the future, please subscribe to and post your questions to the mailing list, and include the relevant error message you're getting.

The following comment has been added to this issue:
Author: John Engstrom
Created: Thu, 8 Jul 2004 3:06 PM
Body:
So why can't I do the following:
int main(int argC, char* argV[])
{
SAX2XMLReader* parser = XMLReaderFactory::createXMLReader();
fudHandlers *handler;
XMLPlatformUtils::Initialize();
handler = new fudHandlers(encodingName, unRepFlags, expandNamespaces);
parser->setContentHandler(&handler);
XERCES_STD_QUALIFIER cerr << "Nuking parser...\n";
delete parser;
delete handler;
XMLPlatformUtils::Terminate();
return 0;
}
It seems that the new operator of the XMLFormatTarget class throws a compile error when you try to do a new handler.
