Hm, I don't.
regression=# select xslt_process('<a/>','<b/>');
xslt_process

(1 row)
regression=# select xslt_process('<a/>','<b/>', '');
xslt_process

I can't see that this would fix anything. A NULL value there is
impossible, and if the string is empty, the loop below should fall out
after properly setting param[0] to NULL. It does look a bit
questionable whether the code does the right thing when MAXPARAMS gets
overrun, but I'm really not seeing what you're seeing. Are you sure
you are using 8.4 and an 8.4 version of xml2?
