Bug Summary and Steps to Reproduce

Just create single main.c file and paste the code.

Expected behavior

Brace next #if 0 should be ignored but it is not.

When I put new line it fine.

And multi line comment also fine.

Code sample and Logs

main.c

int main(void)
{
#if 0 // a
    {
        printf("hello");
#else
    {
        printf("good bye");
#endif
        printf(" world");
    }
}

setting.json

{
    "[c]": {
        "editor.semanticHighlighting.enabled": true,
        "editor.tabSize": 4
    },
    "files.associations": {
        "*.h": "c"
    }
}

no notable output from C/C++: Log Diagnostics and language server.

Additional context

No response

Inizia con la riproduzione di main.c nell’issue e verifica come l’estensione C/C++ gestisce l’evidenziazione semantica delle direttive #if con un commento su una singola riga. Verifica il comportamento con il setting.json fornito e conferma che le parentesi graffe sotto #if 0 siano escluse dall’evidenziazione dello scope, mentre i casi multilinea e con nuova riga rimangano corretti.
