           Summary: c++ parser error
           Product: gcc
           Version: 3.3.1
            Status: UNCONFIRMED
          Severity: critical
          Priority: P2
         Component: c++
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: debian-gcc at lists dot debian dot org
                CC: gcc-bugs at gcc dot gnu dot org

[forwarded from http://bugs.debian.org/203351]

The g++-3.3 parser fails to parse the code bellow with the following error message: 
test.cc:33: error: declaration of `Bitmap::operator GdkBitmap*() const' 
test.cc:23: error: conflicts with previous declaration `Bitmap::operator 
   GdkBitmap*() const' 
 
This code compiles cleanly with g++-3.2. Some changes to the code, e.g. move the  
class Event to the end of the file, makes the file to compile cleanly with g++-3.3. 
 
The problem also exists in current HEAD.

I can confirm this on the mainline (20030729) and 3.3.1 (20030707).
>From Phil's regression hunter:
: Search converges between 2003-06-14-trunk (#313) and 2003-06-22-trunk (#314).
: Search converges between 2003-06-14-3.3 (#145) and 2003-06-22-3.3 (#146).

A binchop with Janis' script shows that the problem was introduced on the
gcc-3_3-branch between 2003-06-17 23:57 UTC and 2003-06-18 00:00 UTC

Mark,

It appears that your patch:

2003-06-17  Mark Mitchell  <mark@codesourcery.com>

      PR c++/11105
      * cp-tree.h (DECL_CONV_FN_TYPE): New method.
      * decl.c (lookup_name_real): Backport conversion operator code
      from mainline.
      * mangle.c (struct globals): Remove internal_mangling_p.
      (write_unqualified_name): Use DECL_CONV_FN_TYPE.
      (write_template_parm): Don't write out the level number.
      (conv_type_names): New variable.
      (hash_type): New function.
      (compare_type): Likewise.
      (mangle_conv_op_name_for_type): Don't try to mangle conversion
      operator names.
      * search.c (lookup_conversion_operator): New function.
      (lookup_fnfields_1): Use it.

has introduced this rejects-valid regression on the branch and mainline.

This is a regression from 3.3.0, so this really should be fixed before 3.3.1
goes out.  Hope it can be done.
