Compiling the test case in the patch with -O2 -m32 without the fix, the program will abort. The problem is a var decl whose address is taken is not marked as addressable leading to bad SSA update (missing VUSE). (the triaging used the the .after and .after_cleanup dump diff and found the problem).
the test is on going. Ok after testing? Thanks, David
