Is it undefined behavior to assign &this to a pointer in the

Yes:
http://dlang.org/spec/struct.html
"A struct is defined to not have an identity; that is, the
implementation is free to make bit copies of the struct as
convenient."
That means it might copy and/or move it without giving you a
chance to update the pointer. Updating in postblit can help
sometimes but still the compiler and library are allowed to
move structs without notice.
You already answered on the IRC so thanks X2.
So, it's problematic to have pointers to structs in all cases
according to spec?
