Can you please attach unwind-c.i ? What exact options is it compiled with (including whatever -march/float abi/etc. is needed to reproduce on say --target armv5tel-unknown-linux-gnueabi configured gcc)? I'm surprised it would affect arm unwind info, but perhaps I've made a bug in the patch somewhere.
