[Bug preprocessor/15307] New: Preprocessor ICE on invalid input

["nisse at lysator dot liu dot se" <gcc-bugzilla at gcc dot gnu dot org>]

gcc-3.4.0, built with ./configure && make bootstrap && make install

Preprocessing crashes with

  bug.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.

when the correct behaviour would be to output an error message

  unterminated argument list invoking macro "ASSERT"

Compilation command line:

  gcc -DWANT_CHECKS=1 -E bug.c

Source file (before preprocessing, but there are no #include
directives in it) is attached.
