Comment(by sjamaan):

 Oddly enough, the following does ''not'' give an error. When I run it, it
 cleanly prints the number 1 on stdout. (well, not that odd, as it's a
 collapsible literal symbol "x", I guess...)

 What I really don't understand is why it doesn't say {{{"error in constant
 evaluation of ~S for named constant ~S"}}} when {{{eval}}} fails. Is the
 syntax-error-hook bound to some odd error handler which quits the compiler
 immediately? If so, any error in eval would cause this to happen, I think?

 {{{
 #!scm
 (define x (foreign-value "1" int))
 (define-constant one x)
 (print one)
 }}}
