ucx_new_team->config is getting leaked here.

this is incorrect, we should consider the parent's stride as well when we want to calculate the new start based on the comm world:
ucx_new_team->start = parent_start + (start * parent_stride)

size can be any positive value , and start is PE index in the parent team, so start < size is not required to be true.

looks good now |
