A call to insert_iterator like a method

That call:

   copy ( x.begin ( ), x.end ( ), f.insert_iterator ( ) );

Produces an internal compiler error:

main.cpp: In function `void copia(set<X,less<X>,allocator<X> > &)':
main.cpp:16: Internal compiler error.
main.cpp:16: Please submit a full bug report.
main.cpp:16: See <URL:http://www.gnu.org/software/gcc/bugs.html> for
instructions.

The attached code produces that error on gcc 2.95.3:
$gcc -v
