Hello Myke,

Sorry for the delay - I've been on vacation.
Ubuntu on ARM comes with a compiler that doesn't generate the ARM 
specific unwind tables by default. I suspect you ran the libunwind 
testsuite against binaries that don't have any unwind infos (DWARF or 
ARM exidx). You may try to compile and run the testsuite like this:
make check CFLAGS="-funwind-tables"

There are still a lot of fails on ARM Linux and any help to get things 
further is greatly appreciated. The Linaro wiki has a page that focuses 
on libunwind on ARM and also shows some testsuite results at the end:
