RE: [Linux-ia64] ias and stack unwind

I don't think that explains it in my case.  I'm using ecc version 7.1.
Did you have to use any special options?

Recently, I have tested libunwind (and readelf -u) with Intel ECC v7.0
and it worked fine.  I'm told earlier versions may have generated bad
(incompatible) unwind info, but I haven't verified that myself.  Could
this explain it?
