While compiling the routine datatypes.cpp in the GDL package, g++ generates an
internal error. This appears to be powerpc specific.
Command line & Error messages follow.

-MD -MP -MF ".deps/datatypes.Tpo" -c -o datatypes.o datatypes.cpp -save-temps

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-3.3/README.Bugs>.
Compiling the included default_io.cpp on its own does NOT generate the error.
Removing the optimization flag genrates a segfault at the same location.
The datatypes.ii file is too large (1.5MB) to attach here and can be obtained
at: ftp://ftp.sr.bham.ac.uk/pub/sjt/datatypes.ii
Since the machine doesn't have problems with other large compiles (e.g. the
Linux kernel) I don't think it's a hardware problem.
