Extended Description

If you compile the attached with -O3, it eventually dies with a complaint about
dataflow masks, similar to bug # 285. This is after WL fusion eventually completes.
However, if you compile it with -noopt, it does compile OK, but 
crashes and burns at runtime with glibc free() invalid pointer.
So, I don't think it's the same bug...
I'll see if I can find a shorter example. This one is 24 lines of APL.
