>Description:
Initially used an hp makefile which included the (unknown?) option -Ae on the command line.  Even with simple "Hello world" source, compiler crashes with segmentation fault.

Compiler output (stdout + stderr):

cc -I. -Ae  -c hw.c
cc: Internal error: Segmentation fault (program cpp0)
Please submit a full bug report.
See <URL:http://www.gnu.org/software/gcc/bugs.html> for instructions.
make: *** [hw.o] Error 1

Source (hw.c) is:

int main()
{
	printf ("Hello world!\n");
}

Command line is:

cc -I. -Ae  -c hw.c

(there are no header files, however)
>How-To-Repeat:
Compile the program with the command line given.
>Fix:
Remove the -Ae option.

Reported because your own documentation says a well-behaved compiler should not crash with invalid input.
