-Relevant analysis:
-
-_int_malloc is inlined into tcache_init, and the allocation size is
-constant-propagated into it.  GCC does not realize that global_max_fast
-is limited MAX_FAST_SIZE, so it compiles the true branch of the if
-statement:
-
-  if ((unsigned long) (nb) <= (unsigned long) (get_max_fast ()))
-    {
-      idx = fastbin_index (nb);
-      mfastbinptr *fb = &fastbin (av, idx);
-      mchunkptr pp = *fb;
-      REMOVE_FB (fb, victim, pp);
-      if (victim != 0)
-
-under the assumption that nb == sizeof (tcache_perthread_struct) == 576,
-which is larger than MAX_FAST_SIZE, so the fastbin access is compiled
-into an OOB array subscript.  GCC does not proceed to eliminate this
-code, even though it has undefined behavior and will never execute in
-practice.
-
-This is neither a glibc bug nor a GCC bug.  It merely reflects the
-difficulty of producing good warnings from optimizers.  But it does
-break the build in rawhide due to -Werror.
