--- Comment #43 from Dimitry Andric <dimitry at andric.com> ---
After importing the latest version of libunwind into FreeBSD (in
https://svnweb.freebsd.org/changeset/base/345018 and
https://svnweb.freebsd.org/changeset/base/345019), this problem is now
*finally* solved.

Specifically, it got fixed by this libunwind commit:

https://reviews.llvm.org/rL292723 ("X86: swap EBP, ESP on !APPLE")
