[Bug c++/30818] New: [4.1.2 Regression] templates and typedefs cause function prototype not to match

2007-02-16 Thread sschunck at pdf dot de 
the following compiled fine on gcc-3.4.6 but gives error on gcc-4.1.2

error: prototype for 'typename AT::B::type AT::B::f()' does not match any
in class 'AT::B'
error: candidate is: typename AT::type AT::B::f()
error: template definition of non-template 'typename AT::B::type
AT::B::f()'


template  typename T  
class A 
{
typedef int type;
class B;

template  typename T 
class AT::B
{
typedef typename AT::type type;
type g() { return 0;}
type f();
};

template  typename T 
typename AT::B::type

( I have no vanilla gcc available, so hopefully gentoo guys did not screw up
gcc-4.1.2 )

[Bug c++/25768] [3.4 regression] wrong code with inlining at -O2

2006-01-12 Thread sschunck at pdf dot de 


--- Comment #3 from sschunck at pdf dot de  2006-01-12 17:04 ---
The miscompiled line is

  (*newchild)-kind = interior; ( interior = 1 )

but when 

 movl$1, (%edx)

is done 

 edx points to 

free_list;

from function MemPool::new_element()

instead of newchild

additional info:
if instruction 
movl$1, (%edx)
would be located two lines later the generated code would be correct (AFAIK)

[Bug c++/18451] New: [3.4 Regression] C++ error message regression

2004-11-12 Thread sschunck at pdf dot de 
The following erroneous code gives an error message I do not understand

file.cc:

  1 template  class T 
  2 class A
  3 {
  4 public:
  5   class B
  6 {
  7   public:
  8   B( int inVal ) :  m_i( inVal ) { }
  9   int m_i;
 10 };
 11   static B s;
 12 };
 13 
 14 template  class T  AT::B AT::s( 10 );



gives the following error message witch g++-3.4.3 -Wall -c file.cc

14: error: expected constructor, destructor, or type conversion before A 
14: error: expected `;' before A

I have difficulties in understancing the message

with g++-3.3.2 -Wall -c file.cc

14: warning: `AT::B' is implicitly a typename
14: warning: implicit typename is deprecated, please see the documentation for
details

This message seems much clearer to me
