Re: Dissector bug

["Rach, Darshan" <DarshanR () nds com>]

I am still unable to solve this issue.
I get the error immediately after executing this piece of code:

reserved = ((tvb_get_guint8(tvb, packet_field_offset) & 0xc0) >> 6);
proto_tree_add_uint(oqtp_tree, hf_reserved, tvb, packet_field_offset, 1, reserved);

Line 1490 in the attached packet dissector code file.

Your inputs would help me a lot :)

Hi,

that usually means you forget to either:
initialize a variable
or didn't add it to the hf[] or ett[] array.

Take a closer look there,

Hi,

I am getting the following error:
[Dissector bug, protocol DASH: proto.c:2457: failed assertion "(guint)hfindex < gpa_hfinfo.len"]

My code looks like this:

static gint hf_epg_info_bits_len = -1;

{&hf_epg_info_bits_len,
{"EPG Info Bits Length","oqtp.epg_info_bits_len",FT_UINT8, BASE_DEC,NULL, 0x0,
"EPG Info Bits Length", HFILL}},

epg_info_bits_len = ((tvb_get_guint8(next_tvb, packet_field_offset)) & 0xf);
proto_tree_add_uint(sub_tree, hf_epg_info_bits_len, next_tvb, packet_field_offset, 1, epg_info_bits_len);
packet_field_offset += 1;

Kindly help.
