Environment OS and version: Linux Mint 22.3 (inside Distrobox) VS Code: 1.114.0 (e7fb5e96c0730b9deb70b33781f98e2f35975036) C/C++ extension: 1.32.2 GDB version: 15.1 Bug Summary and Steps to Reproduce Bug Summary: As far as I understand, IDE + GDB should not call "children" method of a pretty-printer unless the user has asked to expand the value in GUI. Moreover, calling "children" method recursively is unacceptable, because linked data structures can be expanded infinitely. And this is exactly what I see happening in this case: GDB recursively traverses the data structure and hangs because it has loops. Steps to reproduce: Clone this repository: https://github.com/stgatilov/vscode-gdb-pretty-printers-hangs-repro-code Open it in VS Code. Build Debug build. Put breakpoint at the only line of badfunc. Run debugging using the included configuration "Launch with pretty printers". When debugger stops at the breakpoint, GDB hangs trying to evaluate local variable entity. Debugger Configur

Environment VS Code version: 1.115.0 cpptools extension: ms-vscode.cpptools 1.31.4 OS: Windows 11 Compiler: MSVC (Visual Studio Community 2022, amd64) CMake Kit: Visual Studio Community 2022 Release - amd64 Bug Description When debugging a C++ project built with MSVC (VS2022), std::unordered_map<int, float> values are displayed as (,) in both the hover tooltip and the Variables/Watch panel. Steps to Reproduce Declare and populate a std::unordered_map<int, float> variable. Start debugging (via CMake Tools, using cppvsdbg). Hover over the variable or expand it in the Variables panel. Expected Behavior Each entry should display as [key] = value, e.g. [3] = 0.5. Actual Behavior Each entry displays as [3] = (, ). Additional Notes begin()->first and begin()->second both evaluate correctly in the Watch panel, so debug info is intact. The issue appears to be that std::pair::DisplayString expressions ({first}, {second}) fail when rendered as part of unordered_map expansion in vsdbg's natv
