#3  0x0000f0dc in main ()

The segmentation fault is caused by
system__finalization_implementation__deep_tag_attach ()
calling system__finalization_implementation__get_deep_controller ()
with a zero first argument.

I used gcc 4.0.2 as the bootstrap compiler.  I believe that the error
doesn't occur when gcc-3.4.4 is used.
