Actual result (from GDB latest git):

Backtrace stopped: previous frame inner to this frame (corrupt stack?)
The first failing commit is 5b6d1e4fa4fc ("Multi-target support"). The
cause
of the change in behavior is due to (thanks for Andrew Burgess for finding
this):

- inferior_ptid is no longer set on entry of target_ops::wait, whereas
it was set to something valid previously
- deep down in linux_nat_target::wait (see stack trace below), we fetch
the registers of the event thread
https://fintechzoom.com/lifestyle/entertainment/gaming/rimworld/the-best-rimworld-mods/
https://www.nimblehand.com/
https://geoslam.xyz/
- on sparc64, fetching registers involves reading memory (in
sparc_supply_rwindow, see stack trace below)
- reading memory (target_ops::xfer_partial) relies on inferior_ptid
being set to the thread from which we want to read memory
