https://gcc.gnu.org/bugzilla/show_bug.cgi?id=87521 --- Comment #1 from Jonathan Wakely --- The meaning of "user-declared" in C++03 is closer to "has a function body" than the meaning in C++11, where it includes defaulted definitions. A defaulted definition in C++11 is equivalent to an implicit (i

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=87521 --- Comment #2 from Jonathan Wakely --- The C++03 definition of POD struct (which is what matters for the ABI) requires that it has no user-defined destructor. Your type has a user-declared destructor, which is implicitly-defined when odr-used.
