That's no good.  Could you send me a stack trace and explain how you
got that to happen?  I was the last one to touch that code.

In your case, I would definitely set that parameter to false.  For
some reason, OpenCL requires that code and globals be allocated
together contiguously, and because backwards compatibility with them
is somehow more important than doing the right thing, that's still the
default behavior.  See http://llvm.org/bugs/show_bug.cgi?id=4483 .
