The shell is processing
(...)
as a compound command and since the first token is not a typename or
a declaration command or a function definition, it assumes that
it is an array assignment. If fails when it finds the first token
that would make it an invalid array assignment.
However, since an array assignment is not valid for a type definition,
I added another state to the parser so that it produces an error if
the first token is not valid.
I now get:
syntax error at line 2: `xxx' unexpected
in both cases.
Thanks for reporting this.
