All the code involved is unrestricted open source. However, to reproduce the 
bug you'd need to install Python 2.3b1 (also open source) as root. If that's 
acceptable I'd be happy to create a self-contained source code bundle incl. 
instructions. I think it would be worth it because it brings to light some 
other bugs:

- Undefined symbols while linking that (sometimes) go away if the code is 
rearranged.

- Segmentation faults and bus errors when using -O3 instead of -O0.

You could also use our code to verify that the gcc 3.3 optimizer is broken 
under Redhat 8 (where you could use the Python that comes with the OS).

Hello,

I can install the necessary python. If you can e-mail me (or attach to this report) the necessary 
instructions, that'd be great. Thanks,

Dara

The full source for reproducing the internal compiler error is available here:

http://cci.lbl.gov/~rwgk/bugs/mac_os/scitbx_2003_05_26.tar.gz

Unpack and follow the instruction in the file README.

For the records, here is content of the README file:

Regarding:

  http://gcc.gnu.org/bugzilla/show_bug.cgi?id=10922

Under Mac OS 10.2 get and unpack the file

  http://www.python.org/ftp/python/2.3/Python-2.3b1.tgz

and install with the commands:

  ./configure --enable-framework
  make
  make frameworkinstall

The last command requires root privileges because the target directory is:
  /Library/Frameworks/Python.framework/Versions/2.3
"make frameworkinstall" will also create softlinks in /usr/local/bin.
In the following it is assumed that /usr/local/bin is on $PATH and that
the command "python" resolves to /usr/local/bin/python.

It is also assumed that g++ is gcc 3.3.

The internal compiler error is very elusive. Slight changes to the
header files make it go away for certain source code files, and make
it appear for others. Here is what I hope you can use to reproduce
the bug very quickly:

  mkdir build
  cd build
  python ../libtbx/configure.py --build=quick cctbx
  source setpaths.csh
  libtbx.scons cctbx/sgtbx/boost_python/rt_mx.os

If this works for you try:

  libtbx.scons -k .

This will take a while but hopefully you will see a failure for at
least one of the files. The output on my computer is in the file:

  build.log

If for some odd reason everything works on your computer try this:

  mkdir build
  cd build
  python ../libtbx/configure.py cctbx
  source setpaths.csh
  libtbx.scons -k .

This compiles with full optimization (-O3) and results in several
internal compiler errors on my computer.

If you get to the point where all files compile and link without
errors you can run our regression tests with this command:

  python $SCITBX_DIST/run_tests.py

This should show many "OK". It is known to work under Redhat 8 with
both gcc 3.2 and gcc 3.3 (latter with -O0 only, -03 breaks one test).
It also works under Tru64 Unix and IRIX using the native C++ compilers.

About the source code:

- boost (http://www.boost.org/) is the CVS snapshot from 2003-05-26 ca.
  2:15pm Pacific time.

- libtbx, boost_adaptbx, scitbx, cctbx are CVS snapshots of modules in
  the http://cctbx.sourceforge.net/ project.

- scons == SCons 0.14, http://www.scons.org/
  SCons is a build tool (replacing make) implemented in pure Python.
  There is no C++ code in this directory.

I hope this is useful. It took me a long time to put everything together
in a clean way. Please don't hesitate to ask questions about this package:

Hello,

with g++ 3.4, here's the line that yields the first error:

template <class Data>
struct additional_instance_size
{
    typedef instance<Data> instance_data;
    typedef instance<char> instance_char;  
    BOOST_STATIC_CONSTANT(   
        std::size_t, value = sizeof(instance_data)
                           - BOOST_PYTHON_OFFSETOF(instance_char,storage));
};

When preprocessed, it becomes:

template <class Data>
struct additional_instance_size
{
    typedef instance<Data> instance_data;
    typedef instance<char> instance_char;
    static const std::size_t value = sizeof(instance_data) - (reinterpret_cast <
size_t> (&reinterpret_cast <char &>(static_cast <instance_char *> (0)->storage))
);

Preprocessed output is attached to this... 

Thanks,

Dara

The problem with offsetof is now treated in 11072. BTW, where did you read
that the result of offsetof is an integral constant expression? It is not
in my copy of the standard, or at least not at the places I looked at...

I think this problem is that Darwin (Mac OS X)'s stack limit is just set too low.  I will try once I 
download a 3.3.1 (snapshot) compiler.  I know for 3.4 errors out saying you should raise th limit to 
unlimited.  With the limit at 512 I do not get an ICE (Illegal instruction) but it works but with the 
limit set to 100 I do get the Illegal instruction ICE so this really looks like a too low stack limit.

In response to comment #17:

I've confirmed that the compilation of cctbx/sgtbx/boost_python/rt_mx.cpp (see 
comment #5) crashes when using the default stacksize of 512k, but works 
correctly after setting the stacksize to 8192k. -- Ouch!

Thank you very much Andrew!

Darwin stack size limit. I really wonder why the set it so low...

Yup, confirmed fixed when using ulimit unlimited. Note that the testcase still needed 184MB RAM 
to compile. Ouch.
