           Summary: cilk tests ICE in c-array-notation.c
                    (is_cilkplus_reduce_builtin) on mips*-*-*

Test case to reproduce error

A number of cilk tests fail on mips*-*-* due to an ICE.  The ICE happens when
processing the bsearch function from the system include files and is because
we call is_cilkplus_reduce_builtin with a NULL tree.  I am not sure if
is_cilkplus_reduce_builtin should be checking for NULL or if the fact that it
is called with a NULL tree is the problem.

Failure:

mips-mti-linux-gnu-gcc -c -O1 -fcilkplus y.c
y.c: In function 'bsearch':
y.c:19:7: internal compiler error: Segmentation fault
       __comparison = (*__compar) (__key, __p);
