In this regard, you are shallow. I think every developer has a
certain expectation that when they type backtrace, that the debugger
accurately display the data. I was merely referencing a previously
release where it works, and now it doesn't.
There is an obvious difference that this is not working.
I'm all for working towards a solution and I don't think you taking pot
shots at Redhat is working toward that end. If you have a beef with
Redhat, I could care less. If you are saying or implying that this is
broken only in a Redhat kernel, then please be less obtuse, because
I'll gladly track this problem down wherever it may lead.

So it seems that you are well aware of this problem.
Are you recommending that the add-symbol-file-from-memory as the
current solution ?
I've downloaded the current cvs and faced the same problem.
So it seems that a half-solution to this problem which was discovered
and fixed in February, is not even in the current CVS.
If need me to enter it into bugzilla, I'm happy to do that.
Just let me know where.
I researched this problem before posting my findings here.
I'm just looking for developing the correct solution.
Thanks.
