Yes, apparently so.

But with XSLT_REFACTORED defined, compilation fails in preproc.c around
line 423. This makes me wonder if XSLT_REFACTORED is the recommended
setting? Is it any faster / more stable / better tested?

I am not sure if the following change is correct, but at least it
compiles fine and correctly frees all memory which leaked previously:

        case XSLT_FUNC_NUMBER: {
        		xsltStyleItemNumberPtr item = (xsltStyleItemSortPtr) comp;
            if (item->numdata.countPat != NULL)
                xsltFreeCompMatchList(item->numdata.countPat);
            if (item->numdata.fromPat != NULL)
                xsltFreeCompMatchList(item->numdata.fromPat);
            }

Fine here too, no more leaks with the latest changes.

I know. Memory debug is required to show the memory leak trace. It is
turned off for production. Anyway, thanks for pointing it out!
