I was going to mention you don't have to look at .sl.  But it turns out
to be a good idea you did.

You should be able to ignore it.

>One particular .sl file shows errors and also core dumps:

This isn't good.

There should be 2 code offsets then a bunch of bits.
The above last 2 words seems fine.

*** Unwind desc. out of sequence at 0x0009cbd0 in subspace 8 ($UNWIND_START$)
    Desc: 02100006 02bc0002 80881000 00100006  (C$3+0x2063e0e)

Here again the first 2 words are bad.

But I wouldn't think ld would even look at these when linking your a.out.

Yes, that may be the cause.  It may look at the imports.

>What do the errors mean????
>How do we correct them????
Nitin Kashyap

Something is wrong with your shared lib, recreate it and run odump on it.
