IntelliSense gives "No IL" (or crashes) in a certain scenario on macOS #6166
Description
With 1.0.1-insiders, I noticed cpptools become unresponsive, though so far I only repro on macOS (Catalina 10.15.6). Stacks are below. cpptools-srv was at 100%. An IntelliSense update appears to have been stuck. I waited >10 minutes. I have a project that repro's consistently, but reducing it may be difficult.
