Alberto Massari updated XERCESC-777:
------------------------------------
Priority: Major
> XMLPlatformUtils::Initialize() fails to execute any code when called from an shared
> object
> ------------------------------------------------------------------------------------------
>
> Key: XERCESC-777
> URL: http://nagoya.apache.org/jira/browse/XERCESC-777
> Project: Xerces-C++
> Type: Bug
> Components: Utilities
> Versions: 2.1.0
> Environment: Operating System: Solaris
> Platform: Sun
> Reporter: mstorrs
> Assignee: Xerces-C Developers Mailing List
>
> I have compiled Xerces2.1 (stable) on Solaris 2.8 using g++ 2.95.3. The
> samples execute properly. I am linking the xerces.so to another shared object
> I am creating. This shared object is loaded by an application at run time,
> when I call XMLPlatformUtils::Initialize() from the shared object the code
> executes the call, but never actually performs any code within that function -
> I know this because I have editted the Initialize() function and outputed a
> debug statement to a file (this works successfully during execution of one of
> the samples). After Initialize returns, the code continues and then once the
> code tries to execute getDOMImplementation(), the shared object core dumps,
> because the global mutex lock is null, since the new XMLMutex statement is
> never executed within Initialize(). I placed debug statements in this Xerces
> code as well, and know that the function executes, and crashes once the code
> tries to lock to set the cleanupfunction.
> Is there any reason that Initialize wouldn't execute the code?? I have
> attached the shared object code as well as the Makefile. I also tried with
> c++, and that failed the exact same way.
> Here is the shared object code:
> extern "C" unsigned int OBLIX_DLLEXPORT Crap(const char *eventName, ObPPPData
> *data)
> {
> int iStatus = STATUS_PPP_OK; // Return code
> AbstractDOMParser::ValSchemes valScheme = AbstractDOMParser::Val_Auto;
> bool doNamespaces = false;
> bool doSchema = false;
> bool schemaFullChecking = false;
> bool errorOccurred = false;
> try
> {
> FILE *fp = fopen("/opt/netpoint/custom/xerces.txt", "w");
> fprintf(fp, "Before Initialize\n");
> fclose(fp);
> XMLPlatformUtils::Initialize();
> fp = fopen("/opt/netpoint/custom/xerces.txt", "a");
> fprintf(fp, "After Initialize\n");
> fclose(fp);

> catch (const XMLException& toCatch)
