Hi Dave, I don't have a backtrace for the segv... the backtrace is what we want to use libunwind for! :-)
I will try versions 1.1 and 1.0 and see what happens with those. It may take me awhile as my time for this effort is essentially on the back burner. I will let you know.

I don't have a mips machine at the moment (somewhere on my list of things to do). Do v1.1 or v1.0 work for you? There were only a small handful of mips-specific diffs between versions, should be easy to bisect if so. __________________________________________________________________ Confidential This e-mail and any files transmitted with it are the property of Belkin International, Inc. and/or its affiliates, are confidential, and are intended solely for the use of the individual or entity to whom this e-mail is addressed.
