This seems to be extremely sensitive to command line parameters.  E.g. on
mips-sgi-irix6.5 it works (no ICE) with

$ cc1 -E -tditional-cpp include.c -o include.i -I .

When I add either -mabi=n32 or -mabi=64, cc1 aborts.

Similarly, on sparc-sun-solaris2.11:

$ cc1 -E -traditional-cpp include.c -o include.i -I .

ICEs

$ cc1 -E -traditional-cpp `pwd`/include.c -o include.i -I .

works.
