Hi everyone,
Here is another update on the release. I think we're converging
with maybe one new item which I'm a little worried about, as this
touches an area that is traditionally very complex and delicate
(PR gdb/26642).
Fixed Since the Previous Update:
--------------------------------
* [TomT] <PR tui/26638>
TUI focus behavior change
https://sourceware.org/bugzilla/show_bug.cgi?id=26638
Added Since the Last Update:
----------------------------
* [SimonM] <PR gdb/26642>
"maintenance set target-async off" is broken on GNU/Linux
https://sourceware.org/bugzilla/show_bug.cgi?id=26642
Other Ongoing Items:
--------------------
* [EliZ] <PR build/26607>
GDB build failure in gnulib if building on Windows version older than 8
https://sourceware.org/bugzilla/show_bug.cgi?id=26607
gnulib pushed a couple of patches:
https://sourceware.org/pipermail/gdb-patches/2020-September/171920.html
The proposal is the following:
- On the branch: we review, and test the two patches, then
integrate them;
- On master, we schedule a gnulib update.
Patch for the branch proposed at:
https://sourceware.org/pipermail/gdb-patches/2020-September/172155.html
Not Critical, but Requested:
----------------------------
* [<unassigned>] <PR python/26586> (raised by Christian B)
from_tty argument to Python's gdb.execute is no longer effective
https://sourceware.org/bugzilla/show_bug.cgi?id=26586
Not release blocking because not exactly a regressions (8.2 and 9
already had the bug).
Patch pushed to master:
| commit 8f9929bb97dc0f0fdf60269ac8c9a7d50746646f (origin/master, origin/HEAD)
| Author: Gareth Rees <grees@undo.io>
| Date: Sat Sep 26 11:01:45 2020 -0700
| Subject: gdb: Fix from_tty argument to gdb.execute in Python.
Requested second opinion before backporting.
* [AntonK, ShahabV] (suggested by SimonM)
Add ARC Linux gdbserver support
No movement since last update (waiting on path author).
Patch (Aug 26th):
https://sourceware.org/pipermail/gdb-patches/2020-August/171499.html

Hello,
FYI: I am currently investigating a regression caused by 7188ed02d2a7e3fce00a0214e70457c5ef56df6b (Replace dwarf2_per_cu_data::cu backlink with per-objfile map).
With my program it causes GDB to crash with the following backtrace:
#0 __GI_raise (sig=sig@entry=6) at ../sysdeps/unix/sysv/linux/raise.c:51
#1 0x00007fe4e871c8b1 in __GI_abort () at abort.c:79
#2 0x000055e6b5a17333 in handle_sigsegv (sig=11) at /users/mstrasun/sources/gdb/gdb/event-top.c:885
#3 <signal handler called>

<...>
After this patch die_hash ends up being null in this context.

If you can send a reproducer, I can take a look.
