I have now converted my application to link against the .lib file for my dll
(instead of using LoadLibrary) and now my reports of memory leaks are gone.
I still get the memory leaks if I use LoadLibrary, but I don't think this
will be a problem for me. I'm including the VC++ debug output from a run
where I was using LoadLibrary so that maybe someone will be able to explain
this and/or look at fixing it. I'm not sure if it is really a problem or
not, but here ya go. I'm not even calling into the dll, just loading it:

Hi,
I sent this to the list, but it appears that either it did not make it, or I
never received it. That, or I'm terribly impatient. :)

Would you care to include the dump from the output window?

Subject: RE: Memory Leaks (code sample included)
OK, I have managed to get rid of all reports of memory leaks, but I still
think there is either a problem or I don't completely understand something
(probably the latter).
What I did was, in my .exe, removed all references to xerces functions and
just passed in a hardcoded character buffer of XML to my dll. Now I do not
get the memory leak messages.
So, I would like someone to shed some light on this if possible. The
situation I don't understand is if I have the following 3:
1) my exe linked against and making xerces calls
2) my dll linked against and making xerces calls
3) my exe linked against my dll (or loading at runtime with LoadLibrary)
In this case memory leaks are reported.
How can I avoid this assuming that I have no control over the exe that will
be using my dll. My exe is only a test application; the dll is the actual
product I'm working on and I may or may not have control over what the
applications that use my dll will do.
Thanks,
Eric

Hi,
This may not provide any more information, but it would be interesting to
note what happens if you move the XMLPlatformUtils::Initialize() and
XMLPlatformUtils::Terminate() calls into "MyXML.DLL". Then, in the EXE,
call whatever function in "MyXML.DLL" calls XMLPlatformUtils::Initialize()
prior to doing _anything_ related to Xerces - including declaring variables
of types that are part of Xerces (DOM_DOMImplementation)... IOW, make sure
that XMLPlatformUtils::Initialize() is called prior to any constructors
within Xerces, etc...
HTH,
Erik

Thanks for the suggestion, but it didn't seem to have any effect. I'm still
getting reports of leaks.
I don't know if this will trigger any ideas, but I moved my FreeLibrary to
before my Terminate() call and that resulted in even more leaks being
reported by VC++.

Have you tried putting the DOM_Document into an inner scope? I believe the
Xerces shutdown code will not free things if there are reference counts.
In particular, I think DOMStringHandles are not freed. Try this:
int main (void)
{
HMODULE hDllHandle = NULL;
DOM_DOMImplementation impl;
hDllHandle = LoadLibrary("myxml.dll"); // this one causes a leak to be
reported
// hDllHandle = LoadLibrary("mynonxml.dll"); // this one is ok
XMLPlatformUtils::Initialize();
{
DOM_Document doc = impl.createDocument(
0,
"Input",
DOM_DocumentType());
}
XMLPlatformUtils::Terminate();
FreeLibrary(hDllHandle);
return 0;
}
All Xerces objects should be destroyed before you attempt th call
XMLPlatformUtils::Terminate().

Please
respond to
xerces-c-dev
In that case though, why would I not see this if I run my application
without loading the dll? Or even if I load a different dll that isn't using
the xerces libraries?
I'm not quite sure I understand what is going on here.
Thanks,
Eric

Xerces faults in some static data. These can show up as memory leaks to
some
tools, but they are really just static stuff that is faulted in on first
use, but never released until the program ends. If you really want to test
it, load the DLL, do an initital dummy parse, then take a memory snap shot
and check again just before you call terminate. The first parse will cause
all of the lazy faulting in, so if you take a snapshot after that, anything
that shows up in the exit snap shot is a lot more likely to be a legitimate
leak.

Hi,
I'm having a problem with memory leaks under xerces c++ 1.4.0 on Windows NT
using Visual C++ 6.0. I have two different modules using the xerces api.
1) A very small test application that I have written (code below)
2) A dll that is called by this test application, but will eventually be
called by other users (let's call this one 'myxml.dll')
Both of these are linked against the xerces libraries.
