[Bug preprocessor/14103] New: gcc-3.4-20040206.tar.bz2 ICEs on "gcc -E -imacros foo.h baz.c"

["lindsayd at cisco dot com" <gcc-bugzilla at gcc dot gnu dot org>]

I built a native compiler on i686-pc-linux-gnu from
the most recent weekly snapshot, gcc-3.4-20040206.tar.bz2.

The following test makes it seg fault/ICE:
    echo > empty.c
    echo > empty.h
    gcc -E -imacros empty.h empty.c > Efile

      empty.c:0: internal compiler error: Segmentation fault
      Please submit a full bug report,
      with preprocessed source if appropriate.
      See <URL:http://gcc.gnu.org/bugs.html> for instructions.

This does not happen with the compiler I built from gcc-3.4-20040128.tar.bz2, so
it's a regresssion in the last week.

No, the source files don't have to be empty to trigger this. The empty inputs
are my cutdown :-)

Both the 2040206 and 20040128 builds were with GCC sources cpio-merged on top of
binutils-2.14/newlib-1.11.0, and using the configuration options:

--with-gnu-as --enable-languages=c++ --enable-threads --enable-shared
--target=native --prefix=$INSTALL_DIR
