[Devel] find_export("append_hf") - usage?

I tried calling append_hf in the following fashion:

   append_hf( p->req, (char*)elem, 0 );

where p is a tm module TMCB_REQUEST_IN callback, and elem is either
   - char*
   - str*
   - xl_elem_t* generated via
     xl_parse_format( "Header: value", &elem, XL_DISABLE_COLORS );
     (patterned after textops.c:it_list_fixup)

and I get SEGVs in all cases.

Can anyone suggest where I'm going wrong?

(And due to the problems with str*, I believe the code in 
modules/osp/sipheader.c:addOspHeader to be incorrect; comments?)
