Comment # 5 on bug 10983 from 
For the 1.12 branch, the fix is to:

    1) get rid of FT_{U}INT64 fields with BASE_CUSTOM;

    2) put in code to enforce that restriction;

    3) treat the locations where you can only go if those restrictions were
somehow bypassed and where you might not be in the middle of dissection as
locations where g_assert_not_reached(), not DISSECTOR_ASSERT_NOT_REACHED(),
should be called.

For the trunk, I'm working on finishing the earlier changes so that FT_{U}INT64
fields *do* support BASE_CUSTOM; that change would not be sufficient to fix
this in 1.12, a bunch of earlier changes on which it will depend would also
have to be backported.
