Take a look at do_scrub_chars() in gas/app.c.  It processes the input
to eliminate redundant spaces, to simplify the instruction parsing
code.  In your case it has gotten confused by the initial "(1,1)".  It
sounds like your assembly syntax is nonstandard, and will require some
modifications in do_scrub_chars().  There are a number of other
nonstandard syntaxes--look at the various #ifdefs in that function.
