This allows its to be determined if the value has a constructed value - and so can be reassembled. In this case, it is a IMPLICIT constructed OCTET STRING at the presentation layer. Many thanks to Fred Gruman for identifying - and apologies for the delay in commiting.This breaks the ANSI TCAP dissector. It now complains "BER Error: OctetString expected but class:CONTEXT(2) primitive tag:21 was unexpected" and then the packet is marked as unreassembled.
I'm also having problem with this patch. Have a look at this packet which is marked as "[Unreassembled Packet]", while it used to display fine with a "single-ASN1-type" in PRES.
