// Prevent clang-cl/lld-link from discarding DrObject<T>::alloc_ on Windows.
// On COFF targets, clang places the CRT initializer for the template static
// member in the same COMDAT group as the variable itself.  When no code in the
// translation unit takes the address of alloc_ (clang inlines className()),
// the entire COMDAT is eligible for elimination — and lld-link's /OPT:REF
// removes it, so DrClassMap is never populated.
// Explicit template instantiation forces a strong (non-COMDAT) definition,
// which the linker must keep.  This is a no-op on MSVC, GCC, and ELF targets
// (where .init_array entries are GC roots and are never discarded).
