Attached is a patch to solve the CHOICE problem for review.
Problem was two-fold:
1) not passing original class/tag to sub-choice we had matched BER_CLASS_ANY
2) not handling a count==0 if we had matched BER_CLASS_ANY
The patch also includes a my constructed octet string fix again.

Only count the number of items in the SEQUENCE OF IFF we have the full TVB containing the entire blob.
Dont count the items if the tvb is "short" since then this would just lead to a [short frame] before a single item in the SEQUENCE OF has been dissected.
Do we really need to count the items and create a FT_UINT field with the number of items at all?
Then count the items as we are calling the subdissectors and
append the '# item[s]' text to the FT_NONE items after we finished the loop?

desired reported length and the remaining length, so we don't throw an
exception at tvbuff creation time if we don't have all the desired data
- we want to throw the exception at dissection time, so we can dissect
the data we do have.
Use "tvb_ensure_bytes_exist()" to force exceptions to be thrown.
When "dissect_unknown_ber()" is called from "call_ber_oid_callback()",
we're handing it a newly-created tvbuff, so the offset in that tvbuff
should be zero.

Small patch to ber.c
The tcap dissector has been updated to use this length. I have not tested other asn.1 dissectors to ensure that they correctly use the indefinite encoding flag instead of the length value returning zero.
There may also be some problems when re-assembly is needed, but the ability to deal with indefinite length is much more useful.
For developers the get_ber_length now returns the length of the pdu including the EOC, where you have dissectors that use packet-ber.c the eoc may need to be dealt with separately.
The tcap dissector has had numerous changes to make it less cluttered, and the useful feature of the previous version where a dialogue could be filtered out by selecting either the source or destination transaction ID has been incorporated into this version.

-use g_snprintf instead of sprintf and snprintf
-use g_strdup_printf where appropriate
-remove #include "snprintf.h" (as only g_snprintf should be used)
-replace some more alloc/realloc/calloc/free with their glib pendants

that they are not longer than the reported length of the tvb.
this triggers some bugs since in packet-ber we are a bit too lax in setting reported_length of the tvb_new_subset() tvb.
this cause short kerberos packets to not be decoded at all and the same for other short asn based packets as well.
fix some of these instances.

current signature ("class" is a "gint8 *", not a "guint8 *", and "tag"
is a "gint32 *", not a "guint32 *"). Re-generate the dissectors from
the ASN.1 and the .cnf files in the cases where the arguments were fixed
in a .cnf file.
Give some dissectors the right svn:keywords and svn:eol-style settings.

1, start making indefinite length constructions actually work
2, when attempting to decode an unknown BER octet sequence, do not generate [malformed packet] just because the length does not make sense and might point outside the tvb. it might just be that there are implicit tags in the asn1 specification and that it is just impossible to decode the octet stream without knowledge of the asn.

fix bug251 and all other occurances where an oid string passed to packet_ber_object_identifier()
is not defined as foo[MAX_OID_STR_LEN]

- I have had to make some changes to packet-ber to allow for PRIVATE and APPLICATION tags.
- Both ANSI and ITU variants supported without configuration.
- Asn.1 dissectors can now register using an OID value as well as an SSN, the oid it tried first.
