Bug ID: 23514
Summary: target.c: default_thread_architecture: Assertion
failed, while trying to record remote x86_64
Product: gdb
Version: 8.1.1
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: remote
Assignee: unassigned at sourceware dot org
Reporter: emil.gedda at emilgedda dot se
Target Milestone: ---

gdb coredump

By setting `record-full` on a remote qemu-system-x86_64 target and then
continuing, gdb crashes with:

target.c:3132: internal-error: gdbarch*
default_thread_architecture(target_ops*, ptid_t): Assertion `inf != NULL'
failed.
A problem internal to GDB has been detected,
further debugging may prove unreliable.
Quit this debugging session? (y or n) y

This is a bug, please report it. For instructions, see:
<http://www.gnu.org/software/gdb/bugs/>.

default_thread_architecture(target_ops*, ptid_t): Assertion `inf != NULL'
failed.

How to reproduce:

$ qemu-system-x86_64 -S -s &
$ gdb -q
(gdb) target remote :1234
...
(gdb) target record-full
(gdb) c


Which will crash gdb 8.1.1. This happens regardless of what disk image is given
to qemy-system-x86_64
Attached is a lz4 compressed coredump of gdb.
