test case
Trying to get openmp to make a private copy of an array passed
to a function, I tried to use a nested function which produces
the following ICE (recent gcc build from git):
$ ~/src/gcc_build/gcc/xgcc -fopenmp -B ~/src/gcc_build/gcc/ test.c
test.c: In function ‘md_parallel_loop_r’:
test.c:19:11: internal compiler error: in lower_rec_input_clauses, at
omp-low.c:4756
#pragma omp parallel for firstprivate(pos)
