Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.
For Debian GNU/Linux specific bug reporting instructions,
see <URL:file:///usr/share/doc/gcc-3.4/README.Bugs>.

Header files <cln/cln.h> and <ginac/numeric.h> can be found in the
packages libcln-dev and libginac-dev, respectively.

Note that

1) compiler flags "-O -g" are essential, e.g. everything compiles
   fine with "-O2 -g". 
2) both g++-3.3 and g++-4.0 have no such a problem.

Pre-processed code (bzip2 compressed) is attached.

Best regards,
  Alexei
