Thanks for reporting this. We can look into fixing this for our next insiders release.

FYI, a workaround is to generate a launch.json via some other method. You could also set C_Cpp.intelliSenseEngine to "Default" temporarily to use that mechanism to generate the launch.json. Or downgrade to 1.8.4 to create the launch.json. And we have a fix pending at #9771 .

Fixed with https://github.com/microsoft/vscode-cpptools/releases/tag/v1.12.2 -- but FYI, if you don't have a launch.json, you'll need to click the Open launch.json button in the UI that pops up to generate a blank launch.json and then use the Add Configuration button in the bottom right to add a launch.json configuration. The ability to auto-generate the launch.json from the compilers we detect currently requires the intelliSenseEngine to be set to Default.
