            Bug ID: 20657
           Summary: buglet in putop() in opcodes/i386-dis.c
           Product: binutils
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: binutils
          Assignee: unassigned at sourceware dot org
          Reporter: tromey at sourceware dot org
  Target Milestone: ---

This comes from bug 20613 and http://www.viva64.com/en/b/0430/

Here:

        case '{':
          alt = 0;
          if (intel_syntax)
            {
              while (*++p != '|')
                if (*p == '}' || *p == '\0')
                  abort ();
            }
          /* Fall through.  */
        case 'I':
          alt = 1;
          continue;

Either "alt" is assigned twice in succession (in which case the
first assignment could be moved into the "if"), or else the fall-through
is incorrect.
