[Bug translation/33126] New: gimplification failed during stdc++ translation

[torsten at debian dot org]

Greetings, you fearless gcc developers!

While building a cross toolchain for the powerpc-rtems target, I ran into a
gimplification error using gcc trunk as of today:

torsten@pulsar:~/rtems/gnu/gcc$ svn info
URL: svn://gcc.gnu.org/svn/gcc/trunk
Revision: 127649

torsten@pulsar:~/rtems/gnu/gcc$
/home/torsten/rtems/gnu/powerpc-rtems/./gcc/xgcc -v
Using built-in specs.
Target: powerpc-rtems
Configured with: ../combined/configure --target=powerpc-rtems
--prefix=/home/torsten/opt/powerpc-rtems --with-newlib --enable-threads
--enable-languages=c,c++
Thread model: rtems
gcc version 4.3.0 20070820 (experimental)

The host system is Debian unstable as of last week, but I don't think that
makes a difference :-)

Please submit a full bug report,
with preprocessed source if appropriate.

I'll attach the full (preprocessed) source once I get the chance by this silly
web frontend ;-)

Friendly, Torsten
