Comment 4 Keith Seitz 2022-12-02 20:59:54 UTC
Backporting the full patch for gdb/29128 is definitely getting on the highly
invasive side, so I've opted to follow your suggestion, and simply keep the
assertion-to-warning hunk.

I would normally advise people to try GTS, but I see that GTS11 behaves no
better than the system GDB. This patch should land in GTS12 next year.

Would you like to try a scratch build to get you going again?

Verified with gdb-8.2-20.el8.
