System: Linux karma 2.4.9-13 #1 Tue Oct 30 20:11:04 EST 2001 i686 unknown
Architecture: i686
host: i686-pc-linux-gnu
build: i686-pc-linux-gnu

>Description:
g++ gives a bogus error message compiling the source below:
$ cc1plus -quiet x.cc
x.cc: In function `void init_mapping(X<int>*)':
x.cc:9: invalid use of undefined type `struct X<int>'
x.cc:3: forward declaration of `struct X<int>'
Note that the error goes away if the line
mapping[0].first = 0;
is changed to the equivalent
mapping->first = 0;
>How-To-Repeat:
---------------------------------------------------------------
template <class T>
struct X
{
int first;
};
void init_mapping (X<int>* mapping)
{
mapping[0].first = 0;
}
---------------------------------------------------------------
