   This smells like you are getting screwed by this code:

     gdb_test_multiple "continue" "$test" {
       -re "done = 0.*$gdb_prompt " {
	 pass $test
       }
       # other patterns can go here
     }

   There are three occurences of "# other patterns can go here".
   Try changing them to:

       # tcl_syntax_bites_1 other patterns can go here
       # tcl_syntax_bites_2 other patterns can go here
       # tcl_syntax_bites_3 other patterns can go here

   It's a quirk of TCL that comments can occur only in certain places.
   Basically, it's a side effect of the "everything is a block or
   a delayed block" syntax rules.  I bet that the problem would not
   actually happen unless all the "-re" in front of it fell through.

   If that really is the problem, you can fix it as an obvious fix,
   something like:

       # Run around to the done
       # You can add more patterns to this if you need them.
       gdb_test_multiple ...

That's indeed the case.  Thanks!  I'll check in the obvious patch.

   Beats me.  I don't see where the "Undefined command "return"" is
   coming from.  Can you add some "-v" to the invocation of runtest
   and show a gdb.log fragment?

The return is probably the input that is intended for GDB, but doesn't
arrive there.  I'll look a bit further into it, and I'll post the
gdb.log if I don't manage to fix it.

P.S. Since you keep bugging about testsuite results (and rightly so),
     can you tell me the guidelines again?  Was it that you wanted the
     output of:

     cat gdb.sum | grep -v ^PASS

     or something a bit more difficult?
