[Bug preprocessor/24040] New: ICE -Wp,-traditional-cpp in cpp_spell_token at ..gcc/cpplex.c

["rmansfield at qnx dot com" <gcc-bugzilla at gcc dot gnu dot org>]

ICE when -Wp,-traditional-cpp is set. No problem with -traditional-cpp. I don't
know if -Wp,-traditional-cpp is even supported usage because the manual says -E
should be used with -traditional-cpp. 

Testcase:

ryan@avarice:~$ cat small.c
#define foo(a, b) c="a"; d="b";
int main ()
{
char *c, *d;
foo (p, q);
}


ryan@avarice:~$ /home/ryan/bin/gcc -v -Wp,-traditional-cpp small.c
