rcCompactHeightfield area pointer corruption

[GoogleCodeExporter]

In a level which I will give you privately, CompactHeightfield::Build unity 
calls into the native nmcfBuildField which allocates the 
rcCompactHeightField.areas

chf.areas = (unsigned char*)rcAlloc(sizeof(unsigned char)*spanCount, 
RC_ALLOC_PERM);

However before it gets back to c#, Unity frees a bad block of memory which 
seems to cause the area pointer to get nulled.

I am at a loss tracking it down, I could do with a hand. The good news is that 
it is 100% reproducible on my machine at least.

Sorry, this was all our fault, please close the bug.

One of our programmers fixed and unused variable warning by commenting out 

//private IntPtr mSpans = IntPtr.Zero;  // rcCompactSpan[spanCount]

in CompactHeightfield! Whoops
