Hi,
I am trying to cross-compile a recent git snapshot (e09f970) and ran

Hi Sven,
Interesting - thanks for reporting this. Which GCC version are you
using? It looks like your compiler doesn't like te inline asm - the fact
that the third colon is present but the clobber list is empty.
You may try something like this:
--- a/src/arm/Gresume.c
+++ b/src/arm/Gresume.c
@@ -55,7 +55,7 @@ arm_local_resume (unw_addr_space_t as, unw_cursor_t

}
else

I'll prepare a proper patch later today.
Thanks
