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

On Behalf Of Jan Gerbecks 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, Jan On 08.01.2010, at 07:09, Rach, Darshan wrote:
