TShark and fuzz-test.sh don't detect dissector asserts.
The reason is that TShark shows nothing when a dissector assert fails
(DISSECTOR_ASSERT). It should show a similar text as Wireshark does:
09:33:13 Warn Dissector bug, protocol 104asdu, in packet 917:
packet-iec104.c:1109: failed assertion "..."
'fuzz-test.sh' uses TShark and searches for 'dissector bug' in the output. So,
if TShark is fixed, fuzz-test will detect dissector asserts.
