Fact: My code is able to build correctly using non vscode command line and goma build tools. I have copied my c_cpp_properties.json against someone who's C/C++ extension works correctly on this code base and they are identical.
Expect: Features of this extension expected to work correctly.
Actual:

• "Go to definition" frequently sits and spins without producing result. Inconsistently able to work sometimes.
• Inconsistent red underline over everything.
• No autocomplete
• Includes not able to find every file (sometimes it will say it can't find an include, but then "go to definition" will work???).

Reality: It's clear almost no part of this extension works correctly on my machine decreasing my productivity.

Red underline, error: "not a class or struct name"

Try to go to definition, vscode can tell it's a class or struct name. 🤷‍♀️

Red underlines disappear, completely only to come back and underline everything after. Not working correctly at all.
