BTW:
I've noticed some stability problems with xerces-c 1.6 on Solaris 8 with the
same compiler, but this is also true when we were using g++ 2.95.3 for both.
I believe I may have found our problems: We had been using the following
construct to create new documents:
DOM_Document newDocument = DOM_Document::createDocument();
DOM_Node newNode = newDocument.createElement("newchildUsedAsRoot");
newDocument.appendChild(newNode);
whereas we should have been using:
DOM_DOMImplementation impl;
DOM_Document newDocument = impl.createDocument(0, "root", DOM_DocType());
DOM_Element rootElement = newDocument.getElement();
DOM_Element newElement = newDocument.createElement("newchild");
rootElement.appendChild(newElement);
Using an XMLParser on the previous construct led to very nasty
multiprocessor Sparc Solaris crashes, as well as crashes in
DOM_Node::clone(x, true). Prelimary results indicate that the former
construct is VERY erroneous, and that the second seems MP safe. Now that
I've learned about the second construct, it seems silly to have ever written
the first. But we've been using that successfully for quite some time on
NT, and it seems just fine on single processor Sparc Solaris boxen.
