I am not sure if this is a general LLVM bug. It rather seems both Polly 
and AdressSanitizer try to generate an invalid cast. If you can 
reproduce this bug, it should be easy to understand. I would guess there 
is an IRBuilder somewhere in the backtrace, which is used to generate a 
cast. The types are probably incompatible. Unfortunately the backtrace 
from Ryan does not contain any debugging symbols and on the .c
file I cannot reproduce the problem.

Let me know if you found out what was the problem.
