BUG in array assignment #1677
Description
The following code should work, but throws an exception:
dim_t sz = 1;
array a = constant(1.0f, 3, sz, f32);
array b = constant(2.0f, 3, sz, f32);
array cond = constant(0, sz, b8); // all false
a(span, cond) = b(span, cond);
It results in
terminate called after throwing an instance of 'af::exception'
what(): ArrayFire Exception (Invalid input size:203):
In function void assign(cuda::Array<T>&, const unsigned int&, const af_seq*, const cuda::Array<outType>&) [with Tout = float; Tin = float; af_seq = af_seq]
In file src/api/c/assign.cpp:70
Size mismatch between input and output
In function af::array::array_proxy& af::array::array_proxy::operator=(const af::array&)
In file src/api/cpp/array.cpp:498
This seems to be a very corner case: Using sz bigger than 1 works fine. Keeping sz = 1, but using a condition that's not all false also works fine (e.g. using cond = constant(1, sz, b8)). I know empty array handling is pretty new (from #1533), so perhaps there is still an issue handling this case.
