Description

Environment
  • OS and version: Windows 10 22H2
  • VS Code: 1.85.2

Bug Summary and Steps to Reproduce

Bug Summary: When trying to inspect an array for some ada code vscode cppdbg ui locks up and in the "DEBUG CONSOLE" I see "Multiple matches for ..." and I am presented with choices. However I am not able to select any choice using the console or clicking on it. If I use gdb on the command line directly then I can respond with the a selection.

Steps to reproduce:

  1. In this environment...
  2. With this config...
  3. Do '...'
  4. See error...

Research direction

Start by reproducing the issue with VS Code 1.85.2, C/C++ extension 1.3.0, GDB 9.2, and the supplied pipeTransport configuration. Exercise the DEBUG CONSOLE while GDB reports multiple matches and compare it with command-line GDB; done means a user can select a match without the VS Code UI locking up.
