[Solved] Unknown sign: GdbBreakpoint0 after merging d7504a52e3f5f1b6d7f62a006646681bde65a310

[Alexey]

What are the steps to reproduce this issue?

1. :GdbStart gdb -q ./program
2. start
3. break some_object::some_method()
4. continue

What happens?

nvim-gdb crashes:

Error executing vim.schedule lua callback: Vim:E155: Unknown sign: GdbBreakpoint0

What were you expecting to happen?

The program should continue the execution until the breakpoint.

Any logs, error output, etc?

I really want this report to be useful, but, unfortunately, I cannot share any of the nvimgdb.log, proxy.log or spy_ui.log. The code I am working on is not my personal project but a proprietary code related to my job, and I am strictly forbidden to share any logs containing even small parts of this code. Sorry:(

Any other comments?

The issue occurs with neovim v0.9.0 with any commit including d7504a5 and later, but no any problems at all with earlier commits. I currently use 3c3511a, and everything works just fine. If you just go throughout the code step-by-step using next or step commands, everything is fine, but if you let the program run freely using continue, until or finish, nvim-gdb crashes when breakpoints at certain places of code is reached (not all breakpoints lead to crash, but I have a couple of class methods such that if I set a breakpoint at any of these methods and continue until this breakpoint, nvim-gdb will always crash).

I am really sorry for not being able to provide additional logs.

Thanks for the report. I'm unable to reproduce the issue because it is specific to the debugged code. I suggest bisecting the issue by exploring beyond the merge commits and trying to identify the root cause.

I apologize for wasting your time, this is the false report. The issue was not in nvim-gdb itself, but in my ~/.gdbinit. I used this fancy thing called "gdb-dashboard" which adds tons of python stuff to gdb config. After throwing it out of my ~/.gdbinit the issue is not reproducible anymore.
