    DOES THE PROBLEM AFFECT:
        OTHER (please specify)
IDL compilation

    SYNOPSIS:
IDL compiler chokes on valid IDL

    DESCRIPTION:
When I compile the attached IDL file I get the following errors:

tao_idl: "test.idl", line 7: illegal infix operator in expression
tao_idl: "test.idl", line 7: coercion failure  <<  to octet
tao_idl: "test.idl", line 8: illegal infix operator in expression
tao_idl: "test.idl", line 8: coercion failure  <<  to octet
tao_idl: "test.idl", line 9: illegal infix operator in expression
tao_idl: "test.idl", line 9: coercion failure  <<  to octet
tao_idl: "test.idl", line 11: illegal infix operator in expression
tao_idl: "test.idl", line 11: coercion failure  + 2 to octet
tao_idl: "test.idl", line 12: illegal infix operator in expression
tao_idl: "test.idl", line 12: coercion failure  + 4 to octet
tao_idl: "test.idl", line 13: illegal infix operator in expression
tao_idl: "test.idl", line 13: coercion failure  + 8 to octet
processing test.idl
tao_idl: test.idl: found 12 errors


If I read chapter 3.10 Constant Declaration in 
http://www.omg.org/docs/formal/02-06-39.pdf I get the impression that my IDL 
should be valid IDL, as it reads:

An octet constant can be defined using an integer literal or an integer 
constant expression, for example:
     const octet O1 = 0x1;
     const long L = 3;
     const octet O2 = 5 + L;
Values for an octet constant outside the range 0 - 255 shall cause a 
compile-time error.


as e.g (1 << 3) is within the range 0 - 255 and it is valid to initialize an 
octet with "an integer constant expression" I think my IDL is valid.
and the examples c_o11 - c_o13 resemble the example from the OMG document, but 
they fail, too.

    REPEAT BY:
Recompile IDL file with IDL compiler

    SAMPLE FIX/WORKAROUND:
unknown


Here's the IDL

module test
{
  const unsigned long c_l1 = (1 << 1);
  const unsigned long c_l2 = (1 << 2);
  const unsigned long c_l3 = (1 << 3);

  const octet c_o1 = (1 << 1);
  const octet c_o2 = (1 << 2);
  const octet c_o3 = (1 << 3);

  const octet c_o11 = 10 + c_l1;
  const octet c_o12 = 10 + c_l2;
  const octet c_o13 = 10 + c_l3;
};
