there, can you reopen this bug and provide a test case?
> Xerces hangs in ThrowXML
> ------------------------
>
> Key: XERCESC-501
> URL: https://issues.apache.org/jira/browse/XERCESC-501
> Project: Xerces-C++
> Issue Type: Bug
> Components: Utilities
> Affects Versions: 1.7.0
> Environment: Operating System: Windows NT/2K
> Platform: PC
> Reporter: Mikael Widenfalk
>
> I have several threads (CWinThread) that use Xerces. Sooner or later one
> specific thread gets stuck in ThrowXML. The exact point varies depending on
> what
> I send in systemID. This is one example:
> void XMLURL::setURL(const XMLCh* const baseURL
> , const XMLCh* const relativeURL)
> {
> cleanup();
> // Parse our URL string
> parse(relativeURL);
> //
> // If its relative and the base is non-null and non-empty, then
> // parse the base URL string and conglomerate them.
> //
> if (isRelative() && baseURL)
> {
> if (*baseURL)
> {
> XMLURL basePart(baseURL);
> if (!conglomerateWithBase(basePart, false))
> {
> cleanup();
> ----> ThrowXML(MalformedURLException,
> XMLExcepts::URL_RelativeBaseURL);
> }
> }
> }
> }
> [ baseURL = "Client" relativeURL = "Information-1-0.dtd" ]
> The calltree proceeds with:
> msvcrtd!__cxxthrowexcept...@8
> KERNEL32!77e989d1()
> so there are no more clues there I guess. The CPU is at 0% and it appears as
> though everything is stuck in some mutex.
> I've made a (large) test program that spawns 50 threads and parses 50 DTD'd
> XML
> documents in each and it also occasionally gets stucks.
> Brief facts of the case are:
> * Single thread single point of initialization.
> * Uses SAX.
> * New parser, etc. for each document read.
> * Uses MemBufInputSource.
> * Uses MS VS6 sp5.
> Sorry if this provides little clue as to what goes on. Please contact me for
> more specfic information, if needed.
