        <div>
        <pre>Occasionally there are some object files whose orderings violate the
topological sorting requirements.  For example, lldiv.obj from msvcrtd.lib
contains this:

0x1000 | LF_LABEL [size = 8] type = near
0x1001 | LF_PROCEDURE [size = 16]
         return type = 0x0003 (void), # args = 0, param list = 0x1002
         calling conv = cdecl, options = None
0x1002 | LF_ARGLIST [size = 8]

where the LF_PROCEDURE record refers to an LF_ARGLIST record which comes
*after* it.  We currently can't handle this, so we hash the numeric value of
the type index instead of the hash of the other record.  What we should do is
keep a list of records that we couldn't translate, and then try to translate
them on a second pass.</pre>
