I've filed https://github.com/google/syzkaller/issues/1575 to keep track of this. If it detects potential dups, then it could auto-dup as well, but it's not completely trivial (some things are mentioned on the issue). But note it won't help if the bug happens in different functions (e.g. I think lots of bitmap_port_list were actually in different functions). And this is also common for racy bugs -- a racy free catches use in another thread at different locations.
