No.  Have a look at the code.  For example, "struct old_sigaction32" and
"struct new_sigaction32" in signal.c, there is a lot of code duplication
of this kind all over strace code, and some structures are not yet
duplicated thus leading to incorrect multiarch decoding.  I think we
cannot duplicate all structure definitions, thus I call the current
multiarch support inherently unreliable.

The idea of this project is to implement correct multiarch decoding
in a way that would not require manual source code duplication.
