GDB asked me to report the following:

[V Bruce Hunt]

I did a brief search of the bugbase and used the fields "gccbuild:gdb-10.1"
and "component;infrun.c:5690"  along with "internal error".  I got no
intelligible response. Reporting the bug requires a user account, but
creation is restricted.

Below is a copy of the interaction leading to the bug.  I'm happy to share
the full program source leading to the bug.  The bug appears on a 4GB
Raspberry Pi 4 running the latest version of the full version of Raspberry
Pi OS.  I'm using it with OpenOCD to debug a Raspberry Pi Pico through a
Picoprobe. The software is an under-development port of KU Trace by Richard
Sites that uses the Raspberry Pi Pico SDK and the SMP port for the
Pico/Rp2040 of FreeRTOS running on the RP2040 MPU ( A dual core ARM Cortex
V6 processor).

I will report this bug and others that may occur as I work to commission
KUtrace for the RP2040 with FreeRTOS if you think it appropriate by
allowing me to create a gdb bugzilla account.  I have run development teams
at Apple( Apple Consulting Engineering, Apple Integrated Systems) and Adobe
( Director of Engineering, Adobe Photoshop Album, Manager of Internet
Technology for Adobe's Advanced Technology Group.)
