If you are ready to spend potentially lots of time on
such issues, yes...

As for me, I always limit myself to a simple set of (Scheme, in
our current exemple, but it can be applied everywhere) features
with which I can do everything, this way I (most of the time)
avoid these problems with not-very-much-used features which
are less maintained.

This being said, although perhaps not in the implementation
of Guile (as usual...), syntax constructs are a root part of
the Scheme spec, they should work perfectly.

Side note: do you *really* need using the Scheme
syntax ? And why (perhaps there is another way) ?

It looks more like a version problem, but this is a guess.

It seems the error you see [syncase.scm:130:16] is itself located inside
the (error) function of Guile. It would be nice to know what were the
original parameters to (error ...), we would have more info about what
is really happening.
