Variable doesn't get printed through -exec in repl

[Fabian-programmer]

Debug adapter definition and debug configuration

Config based on vscode default with logging
Within vscode this config works and produces the expected result.

local cpptools = mason_registry.get_package("cpptools")

dap.adapters.cppdbg = {
  id = 'cppdbg',
  type = 'executable',
  command = cpptools:get_install_path() .. '/extension/debugAdapters/bin/OpenDebugAD7'
}

Debug adapter version

cpptools v1.14.4

Steps to Reproduce

This error is random, but with following minimal example I could reproduce the error at least every 2nd time. With a more complex example the error occurs all the time. When I reduce the complexity by removing catch2 the error doesn't occur.
It also uses a 3rd party gdb extension. (maybe some timing error?) Edit: this is optional

In vscode it works for me without error.

Now to reproduce:

1. git clone https://github.com/Fabian-programmer/oid_bug
2. g++ -o oid_bug oid_bug.cpp -ggdb -O0
3. Install openimagedebugger (optional)

 git clone https://github.com/OpenImageDebugger/OpenImageDebugger.git
 cd OpenImageDebugger
 git submodule init
 git submodule update
 
mkdir build && cd build
cmake .. -DCMAKE_BUILD_TYPE=release -DCMAKE_INSTALL_PREFIX=../bin
make -j4
make install

GDB integration: Edit the file ~/.gdbinit (create it if it doesn't exist) and append the following line:
source /path/to/OpenImageDebugger/oid.py

4. In oid_bug.cpp set a breakpoint in line 31.
5. Start the debugging with the provided configuration
6. if openimagedebugger is enabled, the variable should be selectable +visible in the ui. But it is also possible to execute -exec print test in the dap repl console, which will return No symbol "test" in current context.

Expected Result

I don't know why I currently can't embed png's here.
But this is the expected result. It should display the variable test inside the open image debugger.

For the -exec print test this is the result from vscode:

--> E (output): {"type":"event","event":"output","body":{"category":"console","output":"1: (10239) ->(gdb)\n"},"seq":1262}
1: (10239) ->(gdb)
--> E (output): {"type":"event","event":"output","body":{"category":"console","output":"1: (10239) 1122: elapsed time 0\n"},"seq":1264}
1: (10239) 1122: elapsed time 0
--> R (variables-22): {"type":"response","request_seq":22,"success":true,"command":"variables","body":{"variables":[{"name":"test","value":"{...}","type":"cv::Mat","evaluateName":"test","variablesReference":1005}]},"seq":1266}

Actual Result

For the actual result the Open Image Debugger window stays blank with the last line in repl:

[OpenImageDebugger] Error: Could not plot variable
--> E (output): {"type":"event","event":"output","body":{"category":"stdout","output":"No symbol "test" in current context.\n"},"seq":100}
No symbol "test" in current context.

repl output for nvim dap

compared to working repl output from vscode

I hope it is ok, that I've just linked everyth. into this repository. Didn't want to clutter the ticket with these outputs.

i have the same problem, when u step in a function the repl doest update, u need for exemple type p test, it will say:-var-create: unable to create variable object, and then type -exec p test, the first command will update the repl i guess

here some information:

I saw that ticket, too. But I was wondering, why it works for me in vscode but not in nvim + the logs look quite different.

[Fabian-programmer]

I switched to gdb 14.1, this issue isn't relevant for me anymore.
Maybe this helps you too @leosmaia21
