Reducing.
Comment 3 Andrew Pinski 2006-09-25 03:19:34 UTC 
reduced testcase:
template <class charT> struct s
{
    charT imp() const;
};
template <class charT> charT s<charT>::imp() const
{
    static const int masks[20] = {0};
}
__extension__ extern template char  s<char>::imp() const;
int regcompA(void)
{
  s<char> t;
  t.imp();
}
Comment 4 Janis Johnson 2007-04-25 18:55:02 UTC 
A regression hunt on powerpc-linux using the reduced testcase from comment #3 with "-g2 -feliminate-dwarf2-dups -finline-functions" identified the following patch:

    http://gcc.gnu.org/viewcvs?view=rev&rev=100802

    r100802 | hubicka | 2005-06-09 16:21:36 +0000 (Thu, 09 Jun 2005)

The failure also occurs with current trunk.
Comment 5 Joseph S. Myers 2008-07-04 21:31:31 UTC 
Closing 4.1 branch.
Comment 6 Jason Merrill 2008-12-04 14:58:36 UTC 
I can't reproduce this with current 4.4 sources.
Comment 7 Richard Biener 2008-12-04 15:17:37 UTC 
The reduced testcase still fails on the 4.3 branch.
Comment 8 Andrew Pinski 2008-12-29 06:56:28 UTC 
A patch was posted to http://gcc.gnu.org/ml/gcc-patches/2008-02/msg00850.html

Maybe some other cgraph changes in 4.4 fixes the problem.
Comment 9 Andrew Pinski 2008-12-29 06:59:10 UTC 
This was most likely fixed for 4.4 by the removal of DECL_INLINE.
Comment 10 Joseph S. Myers 2009-03-31 19:42:58 UTC 
Closing 4.2 branch.
Comment 11 Richard Biener 2009-08-04 12:27:56 UTC 
GCC 4.3.4 is being released, adjusting target milestone.
Comment 12 Richard Biener 2010-05-22 18:11:14 UTC 
GCC 4.3.5 is being released, adjusting target milestone.
Comment 13 Richard Biener 2011-06-27 11:10:24 UTC 
Fixed for 4.4.0.
