[igodard at pacbell dot net]

------- Additional Comments From igodard at pacbell dot net  2004-04-30 01:47 -------
There is at least one case where this construct is used in the standard (at least in the oldish references I have access to). In <bitset> there is (in the gcc 3.4 include files) the following function:
    template<class _CharT, class _Traits, class _Alloc>
      bitset(const basic_string<_CharT, _Traits, _Alloc>& __s,
         size_t __pos, size_t __n) : _Base()
However, according to the SGI documentation this should be:
template<class Char, class Traits, class Alloc>
explicit
bitset(const basic_string<Char,Traits,Alloc>& s,
       size_t pos = 0,
       size_t n = 
         basic_string<Char,Traits,Alloc>::npos)
which is also what C++PL 3rd Edition shows. The initializer "npos" causes gcc to fail with this bug.

FWIW

Subject: Re:  [DR 325] GCC can't parse a non-parenthesized comma in a template-id within a default argument


How funny, the reference is indeed in the standard, it's the last declaration 
on page 502, section 23.3.5.1. Maybe someone can see if there is a defect 
report, though I can't seem to find one if it exists.

It's easy to work around, though, by just duplicating the constructor, and 
having one take the third argument and one not taking it.

The default argument expression can also be parenthesized:

template<class charT, class traits, class Allocator>
explicit
bitset(const basic_string<charT, traits, Allocator>& str,
  typename basic_string<charT, traits, Allocator>::size_type pos =0,
  typename basic_string<charT, traits, Allocator>::size_type n =
  (basic_string<charT, traits, Allocator>::npos));
  ^-extra parentheses--------------------------^

which is perhaps easier.

Sure. That's what the test case was reduced from -- the declaration of the
bitset template ctor :) Has there been any progress on the resolution to issue
325? If the CWG is leaning toward the suggested resolution we might want to file
a library issue to have the bitset ctor declaration changed.

Bangaerth suggested a workaround by duplicating the constructor, one with and one without the argument. But there's an even easier workaround: somply parenthesize the default value. I'd suggest that gcc should do this - although the lexical text of the default is not the same as in the standard, this solutiion preserves the actual default values required by the standard and compiles without error.

Is it really a dupe?  The bug I raised only involved a templated argument, the
class with the member function is not templated.  Besides which, if its invalid
as a member function, why is it not invalid stand-alone?  And why should
typedef's get around it?

because non-member's default args can be parsed immediately, member's
default args cannot be.

>  And why should typedef's get around it?
because those do not have commas in them

I should note this bug is suspended.  This is because the standard is unclear at what is the correct 
behavior.  See DR 325 for all the details.

Some news on that front too:
Additional note (November, 2020):

Paper P1787R6, adopted at the November, 2020 meeting, partially addresses this

Hello.

First, I'm new in gcc.
I'm moving our project on gcc and I meet this bug.

My code:
template <typename T, bool F>
struct sp
{
  sp ()
  {
  }
};

struct X
{
  typedef sp <X, true> sp_x;
  //X (sp_x x = sp_x ())                      // OK
  //X (sp <X, true> x = (sp <X, true> ()))    // OK
  X (sp <X, true> x = sp <X, true> ())        // ERROR
  {
  }
};

Created an attachment (id=14407)
 --> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=14407&action=view)
updated patch

Here's a cleaned up version of Liu Guanwei's patch that passes regression
