Just an FYI for the list, a problem I found that was tricky to find.
The latest (1.1.13) libxslt requires that the mode and mode uri of rhe
transform context be interned within hte transform context's dictionary. I use
to do something along hte lines of:
1: xsltTransformContextPtr ctxt = xsltNewTransformContext(....)
2: ctxt->mode = BAD_CAST "test";
3: xsltApplyStylesheetUser(....., ctxt);
The expected template would never run because libxslt is using pointer compares
without hte fallback to xmlStrEQual. Line 2 needs to be something like:
ctxt->mode = xmlDictLookup(ctxt->dict, "test", -1);
Daniel, would it be possible to have some #IFDEFed debugging that could call
xmlDictOwns() for strings that *must* be interned in the transform dict to
verify their presence? This was a tough one to find because of some sort of
stack corruption caused by it.
