Description Fedor Pikus 2004-12-09 17:19:27 UTC
G++ from RHEL3u2 (gcc version 3.2.3 20030502 (Red Hat Linux 3.2.3-34))
fails to compile this program:
-----------------------------------------------
template <typename T> class A;
int foo( const A<int>& a );

template <typename T> class A
{
    public:
    friend T foo( const A& a ) { return a.x; }
    T x;
};

int main()
{
    A<int> a;
    int i = foo( a ); 
}
-----------------------------------
Error message is:
gccbug.C: In instantiation of `int foo(const A<int>&)':
gccbug.C:14:   instantiated from here
gccbug.C:7: Internal compiler error in regenerate_decl_from_template, at 
   cp/pt.c:9905
Please submit a full bug report,
with preprocessed source if appropriate.

Comment 2 Jakub Jelinek 2004-12-29 17:43:07 UTC
Seems to be fixed by http://gcc.gnu.org/ml/gcc-patches/2003-07/msg01453.html
in GCC 3.3 and backported version of this patch fixes it on gcc-3_2-rhl8-branch
as well. Will add to RHEL3 U5 candidate patches after more testing.

Comment 4 Jakub Jelinek 2005-01-04 17:57:21 UTC
Fix for this has been added to gcc-3.2.3-50, for the time being available from:
ftp://people.redhat.com/jakub/gcc/3.2.3-50/
