Stream filter error signaling
act_ks_value
returns NULL if a filter fails to parse its input, and as a result xrefs
will be NULL
in act_xrstm
, which it inserts into the results, ultimately the NULL making its way into the xrefs in memory. !17 (merged) fixes this with xref streams, where you want the parsing to abort, but there could be more inconsistencies from act_ks_value returning NULL
.
