Failing .ll file

I'm seeing an assert from the InstructionCombining pass.  It attempts to fold
the following:

IC: ConstFold to: 
i8 addrspace(12)* getelementptr inbounds ([4 x i8] addrspace(12)* @buf,i32 0,
i32 2) 
from:
%ptr = getelementptr inbounds i8* bitcast ([4 x i8] addrspace(12)* @buf to
i8*), i32 2

As you can see it changes the types and thus the RAUW fails.  To reproduce run
"opt -instcombine min.ll"</pre>
