Hi,
There is sth weird when I am debugging a new
dissector in Ethereal. During debugging, the execution order of program
statements is not following the program flow. For example, in the following
capture of debugging session, it jumpped around the statement 2105 quite a few
times until finally execute it. I have never met such problems with GDB.
By the way, after I successfully dissect the
first two packets in the dump file, the program suddenly aborted because of
failing on the following assertion: ** ERROR **: file tvbuff.c: line 379
(check_offset_length_no_exception): assertion failed: (tvb->initialized).
Could anybody help me out here?
Many thanks!
Michael
PS: A sample debugging session:
2105
gchar * pdu_type_string = val_to_str(pdu_type, pdu_types,
(gdb)
n
2092 {
(gdb)
n
2105
gchar * pdu_type_string = val_to_str(pdu_type, pdu_types,
(gdb)
n
2097 gchar * str = NULL;
(gdb)
n
2101
proto_tree * argu_tree = NULL;
(gdb) print pdu_type_string
$14 = (gchar *)
0x0
(gdb)
n
2102
proto_tree * subtree = NULL;
(gdb)
n
2105
gchar * pdu_type_string = val_to_str(pdu_type, pdu_types,
(gdb)
n
2108 ret

(gdb) print
pdu_type_string
$15 = (gchar *) 0x0
(gdb)
