ARM binary executable, tinyhttpd web server
The following text is printed by GDB when executing stepi in a while loop using
a gdb script.
0xf67e3020 in ?? ()
1: x/i $pc
findvar.c:292: internal-error: value_of_register_lazy: Assertion
`frame_id_p (get_frame_id (frame))' failed.
A problem internal to GDB has been detected,
further debugging may prove unreliable.

The setup is an ARM binary run using qemu-arm-static user emulation.
qemu-arm-static -g 1234 ./httpd 8888
The -g option to qemu starts a gdb stub which is first connected to, before
setting a breakpoint, continuing, and then executing a long series of stepi
instructions before the bug is exercised. I'll attach the binary in case it is
of any use. Note: if you try to run this and get as far as actually running
the executable, you'll have to actually submit a request to the server (e.g.,
with curl) to exercise the bug.
