Yes, there are solutions, and the simplest one is replace the direct vtable lookup with an indirect one where the methods are referenced not by their numeric offsets in the vtable but via their symbolic names and the offset resolution is performed via a separate lookup table – not that dissimilar from how it is done in ELF shared libraries.

All of them will result in incurring a performance penalty, either at the runtime, or at the start-up time, or in the compiler/linker, and memory blowouts. But it will solve the recompilation problem.
