http://codereview.appspot.com/5272048/diff/18001/tree-asan.c#newcode325 tree-asan.c:325: base = build_addr (t, current_function_decl); There are issues with creating address expressions from TARGET_MEM_REF in gcc. Since you want compiler to do optimization on instrumented code as much as possible, asan instrumentation is better done as early as possible after ipa inlining -- and this will also solve this problem. I tried moving asan pass before loop opt, and it worked fine. http://codereview.appspot.com/5272048/
