BUG: Windows NT Version 4.0 Bug List - MIDL (165280)

MORE INFORMATION

MIDL does not resolve ambiguous references using the same search order as mktyplib. MIDL: Arrays bigger than 64k not supported as IDL pipe elements Exception 0xC003005E may occur when using big fix-sized arrays with RPC pipes. MIDL generates code that uses an undeclared variable when interface procedure contains a two dimensional matrix as an out param in -Os mode. MIDL: AV when union with no switch is embedded in a struct referred to by a forward reference. MIDL only allows predeclid to be applied to properties. MIDL allows multiple types mapped to the same user_mrsh type. MIDL: Pointer to pointer to struct may cause server side memory leak. MIDL: Overloading some intrinsic types in a type library generates an error. MIDL does not support commas in constants localized for German, etc. MIDL: Inferring pointer decoration differs between DEC idl compiler and MIDL. MIDL: structs with conformant varying arrays of structs not marshaled properly. MIDL: TCHAR typedef should be removed from wtypes.idl as misleading TCHAR typedef'd in wtypes.idl as WCHAR even if UNICODE is not Defined. MIDL accepts duplicate uuids for structs. MIDL: may compute wrong struct size for struct containing user_marshal types at -Zp4. MIDL: helpstrings not placed on functions with multiple put properties. MIDL: dispinterface, interface conflict in coclass not flagged. MIDL: /win16 switch places _stdcall instead of _cdecl on all methods when processing a library block. MIDL: unused typedefs inside of an interface definition are not emitted to type library. MIDL: Full pointer to a user_marshal type, when used in a non-object interface in a struct or union, is overwritten if declared [in,out]. MIDL: Should generate a warning when conformant structs passed by Value. MIDL: Range checking should be applied to constants. MIDL: DCE error codes for pipes not supported.

The following problems have been fixed in MIDL version 3.1.75: MIDL allows importlib outside of library block. MIDL: Interop problems with OSF machines when [comm_status, fault_status] only specified in acf file. MIDL: emits code that initializes a const variable with 0xff. MIDL: Name of coclass used instead of typedef'd name specified in Odl. MIDL: Signed negative constants are emitted to header file with two preceding '-' signs. MIDL: const floating point constants placed in quotes, but '-' sign placed outside the quotes. MIDL doesn't support helpstringdll attribute.
