    I spent couple of minutes trying to see what's going wrong, and
    I didn't found something very conclusive.

    However, looking at the  code of search_command, I'm wondering why
    an error could  be output even if  noerror is t or a  symbol [1] ;
    fixing this that way :

        if (lim > ZV)
        lim = ZV, lim_byte = ZV_BYTE;
        else if (lim < BEGV)

        lim = XINT (bound);
        if (n > 0 ? lim < PT : lim > PT)
!       {
!         if (NILP (noerror))
!           error ("Invalid search bound (wrong side of point)");
!         return Qnil;
!       }
        if (lim > ZV)
        lim = ZV, lim_byte = ZV_BYTE;
        else if (lim < BEGV)


    would fix the reported bug.

    But I don't  know if c-indent is supposed to  pass a wrong `bound'
    to c-syntactic-re-search-forward...

    Bye.
