State-Changed-Why:
Your testcase is not standalone and needs all sorts of
files in order to compile properly.
Please read the instructions at http://gcc.gnu.org/bugs.html
and submit preprocessed source.

>Description:
Internal compiler error, happens in both g++-2.95.4 and g++-3.0.4.
I was attempting to produce a test case for some lockups that
were happening when I wrapped a c++ library which used iostreams
in an xsub so it could be called from perl. The test case
produced an internal error.
>How-To-Repeat:
I am including both the file Conflict.xs with the original code,
and the generated Conflict.c file (really a c++ file) with the
c++ code. The compilation command which originally produced the
error was:
g++ -c -DDEBIAN -fno-strict-aliasing -I/usr/local/include -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -O2 -DVERSION=\"0.01\" -DXS_VERSION=\"0.01\" -fPIC -I/usr/lib/perl/5.6.1/CORE Conflict.c
I tried again with all the flags except for -I/usr/lib/perl/5.6.1/CORE
removed, and the behavior was the same.
