Re: What are the preconditions of newArray#

stg_newArrayzh in rts/PrimOps.cmm doesn't appear to give any indication, so this might be a good patch to add. But I'm curious: what would allocating Array#s of size 0 do? Null pointers? That sounds dangerous... Edward Excerpts from Johan Tibell's message of Fri Aug 19 11:04:48 -0400 2011:

Hi,

I'm seeing a segfault which I suspect is due to allocating Array#s of size 0, using newArray#. Are zero length arrays allowed? What are the preconditions of newArray#? It'd be great if they were documented.
