[Bug c++/20025] New: Internal error while compiling

[sjt at star dot sr dot bham dot ac dot uk]

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.
g++ -DHAVE_CONFIG_H -I. -I. -I.. -I/usr/include/python2.3  -O2  -MT datatypes.o
-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.

I cannot duplicate this with GCC 3.3.3 on AIX, GCC 3.3-hammer on SLES9, GCC 
3.4.4 on SLES9, or GCC 4.0 on SLES9.  This may have been introduced after GCC 
3.3.4 or 3.3.5, but it appears to have been fixed in more recent releases.

Is this fixed in 3.4.x as 3.3.x is no longer supported.  And David could not reproduce this in 3.3.3 and 
3.3.4.
