[Libunwind-devel] In the Linaro environment ...

[Myke Smith (Palm GBU)]

Ken,

When running the libunwind test suite on ARM I am getting a large number of 
failures. What is  the expectation and what do you see in your environment? 
Before I start digging in with GDB I want to see if this is expected or not.

This is what I get:
