Hi,

While reviewing some change in xsltCompileIdKeyPattern, I noticed that there might be missing xmlFree:


current git source from line 1453:

    } else if (xmlStrEqual(name, (const xmlChar *)"processing-instruction")) {
	NEXT;
	SKIP_BLANKS;
	if (CUR != ')') {
	    lit = xsltScanLiteral(ctxt);
	    if (ctxt->error) {
		xsltTransformError(NULL, NULL, NULL,
			"xsltCompileIdKeyPattern : Literal expected\n");
		return;
	    }
	    SKIP_BLANKS;
	    if (CUR != ')') {
		xsltTransformError(NULL, NULL, NULL,
			"xsltCompileIdKeyPattern : ) expected\n");
		ctxt->error = 1;
                !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
		return;
	    }


Instead of the exclamation marks I believe there should be xmlFree(lit);

I have no reproducible case or anything, it's just pure observation of the code, so I might be wrong.
