Another NULL pointer on the same brick. I suspect soemthing could be
rotten here, but what?

Program terminated with signal 11, Segmentation fault.
#0  pl_truncate_cbk (frame=0xbaf24f10, cookie=0xbaf01b00, this=0xba554000, 
    op_ret=-1, op_errno=22, prebuf=0xb98e6c70, postbuf=0xb8fffaac)
    at posix.c:117
117             if (local->op == TRUNCATE)

local is frame->local and is indeed NULL.

(gdb) print *frame
$2 = {root = 0xbad010ac, parent = 0xbaf0b5b0, next = 0xbaf0b5b0, 
  prev = 0xbad01120, local = 0x0, this = 0xba554000, 
  ret = 0xbba0df38 <iot_ftruncate_cbk>, ref_count = -1, lock = {

    tv_sec = 0, tv_usec = 0}, end = {tv_sec = 0, tv_usec = 0},
