From FEDORA_PATCHES Mon Sep 17 00:00:00 2001
|
||||
From: Guinevere Larsen <blarsen@redhat.com>
|
||||
Date: Mon, 22 Jan 2024 10:13:52 +0100
|
||||
Subject: gdb-rhbz2259850-list-period-crash-fix.patch
|
||||
|
||||
;; Backport gdb: fix "list ." related crash
|
||||
|
||||
When a user attempts to use the "list ." command with an inferior that
|
||||
doesn't have debug symbols, GDB would crash. This was reported as PR
|
||||
gdb/31256.
|
||||
|
||||
The crash would happen when attempting to get the current symtab_and_line
|
||||
for the stop location, because the symtab would return a null pointer
|
||||
and we'd attempt to dereference it to print the line.
|
||||
|
||||
This commit fixes that by checking for an empty symtab and erroring out
|
||||
of the function if it happens.
|
||||

||||

|
||||
Subject: gdb-rhbz2261580-intrusive_list-assertion-fix.patch
|
||||
|
||||
;; Backport upstream workaround for GCC 14 problem which cause assertion
|
||||
;; failures in GDB.

|
||||
[gdb/build] Workaround gcc PR113599
|
||||
|
||||
Since gcc commit d3f48f68227 ("c++: non-dependent .* operand folding
|
||||
[PR112427]"), with gdb we run into PR gcc/113599 [1], a wrong-code bug, as
|
||||
reported in PR build/31281.
|
||||
|
||||
Work around this by flipping inherit order:
|
||||
...
|
||||
-class thread_info : public refcounted_object,
|
||||
- public intrusive_list_node<thread_info>
|
||||
+class thread_info : public intrusive_list_node<thread_info>,
|
||||
+ public refcounted_object
|
||||
...
|
||||
|
||||
An argument could be made that this isn't necessary, because this occurred in
|
||||
an unreleased gcc version.
|
||||
|
||||
However, I think it could be useful when bisecting gcc for other problems in
|
||||
building gdb. Having this workaround means the bisect won't reintroduce the
|
||||
problem. Furthermore, the workaround is harmless.
|
||||
|
||||
Tested on Fedora rawhide x86_64.
