[LLVMdev] Sporadic "RealOffset <= INT32_MAX && RealOffset >= INT32_MIN" failures with MCJIT on Windows

[Nicholas Chapman]

There was a crash on Windows when more than 4K is allocated on the stack 
at once, due to chkstk call offset being too large.  Maybe you are 
seeing that.
It's fixed in trunk, but not in any stable release.
