vector::insert has race conditions #331

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
vector_base::fill_insert and vector_base::range_insert have race conditions 
because they use copy on overlapping ranges.

We need to detect when the ranges overlap and copy to and from a temporary in 
this case. We should eliminate thrust::detail::move and introduce 
thrust::detail::potentially_overlapping_copy and 
thrust::detail::overlapping_copy. Host code can probably ignore this case for 
now.
