The only actual accesses to the memory are through an "int *" pointer and a "long *" pointer, and there's a placement new between the two. I thought the whole point of these patches was to allow placement new to change the type in exactly this way? -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=29286
