will,

i didn't try to interpret your memory debug, but took a look at
diversion header parsing code.  like many other header parsers, it is
using parse_to() function and there is in hf.c/clean_hdr_field()
function case 

		case HDR_DIVERSION_T:
			free_to(hf->parsed);
			break;

so i didn't find anything specific to diversion header parsing that
could explain a leak.  it doesn't mean that there couldn't be a problem
somewhere else.
