[Openmcl-devel] Crash on allocating new pointer

[Andrew P. Lentvorski, Jr.]

Okay, after digging way down and finding %new-ptr, malloc, and free, I 
attempted to use %new-ptr to give me a cleared block of memory so that 
I could at least guarantee that the int I was passing was a zero.  
However, it tosses an illegal instruction exception.

What did I do wrong this time?
