So it's this assert added here:
https://sourceware.org/git/?p=binutils-gdb.git;a=commit;h=249d08128787e4e0a977079aa09516d73f196f77
For some reason, the threads created for your core are marked as exited
(we can even see the [LWP n exited] notifications). That probably
shouldn't happen for a core. It's really odd that the same threads keep
exiting and reappearing. You'll need to dig into that.
Can you open a bug on bugzilla for this? It would help if you could
attach a core file and the associated binary.
