Preprocessed output from the source files that reproduce this bug

(I'm re-filing this bug per suggestion from the downstream Ubuntu bug tracker:
<https://bugs.launchpad.net/ubuntu/+source/gcc-4.6/+bug/1093055>  Upon further
investigation, the bug doesn't appear to be Ubuntu-specific.)

I've hit this bug on several g++ versions, but am primarily running 4.6.3 as
bundled with Ubuntu 12.04, on a relatively stock system:

Description:    Ubuntu 12.04.1 LTS
Release:    12.04

I'm trying to compile a particular source file. When I compile it as follows, I
get the following error:

$ g++ -I ../include -I HelperLibraries -g -Wall -Wno-unused-value -shared -fPIC
-o build/BasicIntegerParser_continuous.so
ParserFunctions/BasicIntegerParser_continuous.cpp ../include/Vertica.cpp
ParserFunctions/BasicIntegerParser_continuous.cpp: In member function âvirtual
Vertica::UDParser*
BasicIntegerParserFactory::prepare(Vertica::ServerInterface&,
Vertica::PerColumnParamReader&, Vertica::PlanContext&, const
Vertica::SizedColumnTypes&)â:
ParserFunctions/BasicIntegerParser_continuous.cpp:76:16: internal compiler
error: in build_zero_init_1, at cp/init.c:279
Please submit a full bug report,
with preprocessed source if appropriate.
See <file:///usr/share/doc/gcc-4.6/README.Bugs> for instructions.
Preprocessed source stored into /tmp/cc8HZt1y.out file, please attach this to
your bugreport.

I expected the file to compile properly, or at least provide an error message
describing a fault in my code rather than in the compiler.

I have attached the preprocessed source file as requested by the error message.

The error reproduces for me on g++ 4.4.5 (installed on top of Red Hat
Enterprise Linux -- hence concluding no Ubuntu dependency).  Others have
reproduced this with both vanilla and Ubuntu-packaged g++ 4.7.2.

The bug does NOT reproduce for me on g++ 4.1.2; the above code compiles and
runs as I would expect:

$ gcc -v
Using built-in specs.
Target: x86_64-redhat-linux

--with-java-home=/usr/lib/jvm/java-1.4.2-gcj-1.4.2.0/jre --with-cpu=generic
--host=x86_64-redhat-linux
Thread model: posix
gcc version 4.1.2 20080704 (Red Hat 4.1.2-52)

The code also compiles and runs as I would expect under clang 3.0.  (I suspect
that's not too useful for debugging, but, just in case / to be thorough.)

Please let me know if I can help out in debugging or fixing.
