re PR middle-end/59152 (ICE: loop 2's latch does not have an edge to its header with -fopenmp -fipa-pure-const)
PR middle-end/59152
* omp-low.c (expand_omp_for_static_chunk): Don't set loop->latch
for the inner loop if collapse_bb is non-NULL.
(expand_omp_simd): Use cont_bb rather than e->dest as latch.
* c-c++-common/gomp/pr59152.c: New test.
