Hello,
can you print hentity and *hentity in frame 1?
Cheers,
Daniel

I see that core_hash has moved from /lib/kcore/hash_func.h (in 3.2) to

passing a null or uninitialised string?
after getting the debug symbols, i see this:

(gdb) print hentity->pres_uri
$1 = (str *) 0x7fe3b1866a01
looks like that str does not point to anything real:
(gdb) print hentity->pres_uri.len
$3 = 1835890035
(gdb) print hentity->pres_uri.s
$4 = 0x2d6567617373656d <Address 0x2d6567617373656d out of bounds>
