it
All information needed to reproduce the issue

Dear GDB developers,

when debugging a remote RISC-V target, I have run into the following assert=
ion:

../../binutils-gdb/gdb/infrun.c:5692: internal-error: int
finish_step_over(execution_control_state*): Assertion
`ecs->event_thread->control.trap_expected' failed.
A problem internal to GDB has been detected,
further debugging may prove unreliable.


Step-by-step instructions how to reproduce it are attached, and the scenario
utilizes:=20
- Spike RISC-V ISA simulator as the actual target
- OpenOCD as the gdb server

Background: The actual scenario has been encountered when running this
automated RISC-V debugger test suite
(https://github.com/riscv/riscv-tests/tree/master/debug) but has been isola=
ted
and instructions written up how to re-create the scenario manually via seve=
ral
simple steps (see the attached .txt file).

Attached is also information about the environment in which I encountered t=
his
problem.

If there are more useful details that I could provide, please do let me kno=
w.

Kind regards,
Jan
