--- Comment #1 from Dimitry Andric <dim@FreeBSD.org> ---
Hm, the problem is to figure out what the value of 'encoding' is at that po=
int.
 In libunwind trunk I see no change in the getEncodedP() function, so it's
definitely not supported by a newer version of libunwind either.

Another possibility is that the unwind information gets mangled somehow (ma=
ybe
by the linker, or by stripping?) causing libunwind to become confused.

Ed, any ideas?
