My assumption is that you have some driver code or preloaded DSO that
effectively implements `copy_to_amdgpu`, which would do something with the
symtab.
Can you just make your driver not be asan-ified (either by not building it with
`-fsanitize=address` or using `__attribute__((no_sanitize("address")))` on the
`copy_to_amdgpu` function? Then you'd copy the right quantity of data, and the
access of the redzone would be ignored as there's no instrumentation there.
This seems like a more appropriate thing than making `st_other` symtab entries
not actually the right size.
