Ken, Thanks, I am on vacation at the moment, I will work on this when I return..
I do not explicitly call out -funwind-tables but when I run you variant of debuggerd I do get everything to correctly backtrace even with stripped binaries which implies to me that the unwind-tables were being generated. Thanks for your work on this and I will dig back in on my return. -myke On Oct 11, 2011, at 7:24 AM, Ken Werner wrote: > On 09/26/2011 05:53 PM, Myke Smith (Palm GBU) wrote: >> Ken, >> >> When running the libunwind test suite on ARM I am getting a large number of >> failures.
