This error message means that:
wordexp(str, &result, WRDE_NOCMD|WRDE_DOOFFS)
is returning WRDE_SYNTAX on your system. According to wordexp(3), this
means:
WRDE_SYNTAX
Shell syntax error, such as unbalanced parentheses or
unmatched quotes.
wordexp here is being used to parse the command that ssh is sending under
the hood when you scp. Apparently there's something about that FreeBSD
wordexp doesn't like, or somehow the command line is being parsed
incorrectly.
My bet on why this is succeeding outside the chroot and not succeeding
inside the chroot is this tantalizing statement in the FreeBSD wordexp(3)
man page:
The wordexp() function is implemented as a wrapper around the
undocumented wordexp shell built-in command.
I'll bet that /bin/sh in your chroot is not the same as /bin/sh outside
your chroot, it's not recognizing this shell built-in, and libc is
incorrectly interpreting this as a syntax error.
