Bug ID: 30240
Summary: (linux/aarch) thread.c:86: internal-error:
inferior_thread: Assertion `current_thread_ !=
nullptr' failed.
Product: gdb
Version: HEAD
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: gdb
Assignee: unassigned at sourceware dot org
Reporter: dmitry.neverov at jetbrains dot com
Target Milestone: ---
Created attachment 14755
--> https://sourceware.org/bugzilla/attachment.cgi?id=14755&action=edit
gdb.output
Cannot debug simple hello world with gdb 13.1 or gdb built on commit
bf8d2f92356768d329430c08dc81025243db636d (note that it includes the last commit
fixing https://sourceware.org/bugzilla/show_bug.cgi?id=26761). Gdb 12.1 which
comes with ubuntu 22.04 works fine. If that matters, it happens on ubuntu
installed in parallels on mac.

Just to confirm, does the target machine support Pointer Authentication? When
you say mac, is this M2-based?

--- Comment #3 from Luis Machado <luis.machado at arm dot com> ---
For the record, I've seen this particular internal error happening in other
cases, so it may not be exactly the issue with pauth handling for the aarch64
backend, hence why I wanted to confirm.

--- Comment #4 from Dmitry Neverov <dmitry.neverov at jetbrains dot com> ---
I use Apple M1 Max. According to [1], Pointer Authentication is disabled by
default and I didn't enable it. The document says it should work inside a linux
VM anyway. Disasm for main or _start doesn't contain any pacio/autia
instructions.

Thanks for the info. For the pauth-related problem, a fix is under review and
should hopefully make its way to master and gdb 13 soon.

I've pushed a fix to gdb master and gdb 13 for the pauth issue. Could you
please verify it works now (if this is the bug you were hitting).
