lldb-mi hangs and starts consuming more and more memory when stopping at certain breakpoints in vscode-cpptools

[mlangiu]

Hi, I wanted to notify you of several issues that crop up with debugging via the cpptools package for Visual Studio Code, which appear to be caused by an error in lldb-mi.
In summary stopping at (or in some cases near) uninitialized memory.
More details can be found in the following related issues

• lldb-mi becomes unresponsive, uses lots of memory microsoft/vscode-cpptools#1899
• LLDB debugger hangs (using 100% cpu) at launch if std::map is uninitialised  microsoft/vscode-cpptools#5805
• lldb-mi freezes on MacOS when breaking near uninitialised variables microsoft/vscode-cpptools#7240

I hope I came to the right place.

Kind Regards

Marco

lldb-mi is no longer a part of lldb. You can try filing a bug here https://github.com/lldb-tools/lldb-mi, but I don't know how active the project is. Feel free to file a new bug if you're able to reproduce the problem with lldb alone.
