Bug Summary and Steps to Reproduce

Bug Summary:

The pointer variable test2 is mistakenly squiggled (pointer to incomplete class type), though location of an include file that declare the TestStruct2 struct is explicit.

By opening test.h and going back to test.c, the squiggle disappears.

Note1: The struct of pointer variable test1 is also declared inside the include file, that is not squiggled.
Note2: The problem is also true on Linux with gcc.

Steps to reproduce:

1. Place the test.h and test.c (inside test.zip) at the same directory
2. Open test.c with VSCode
3. Wait C/C++ extension process finish
4. See error

Expected behavior:

The squiggles should not appear.

Inizia con i file test.c e test.h dell’allegato test.zip e riproduci le diagnosi dopo aver aperto prima test.c e poi test.h. Confronta il comportamento di IntelliSense e i log per test1 e test2; il lavoro è completato quando il puntatore valido di test2 non riceve più una sottolineatura ondulata per classe incompleta quando la relativa dichiarazione inclusa è disponibile.
