Description
Bug type: Language Service
Describe the bug
- OS and Version: doesn't matter
- VS Code Version: doesn't matter
- C/C++ Extension Version:
v1.6.0 - Other extensions you installed (and if the issue persists after disabling them): doesn't matter
- If using SSH remote, specify OS of remote machine: doesn't matter
- A clear and concise description of what the bug is, including information about the workspace (i.e. is the workspace a single project or multiple projects, size of the project, etc).
This should be a valid c++ syntax:
(not sure if this has been reported before)
constexpr char STA_SSID[] =
#include "ssid.txt"
;
Expected behavior
No error reported

Research direction
Start by reproducing the shown C++ snippet in the C++ language service and inspect the diagnostic produced at the #include line. Trace how the language service handles an include used as the initializer for a constexpr char array. Done means the valid snippet produces no “Expected an expression” error.
