Hello. If you put the following in a C mode buffer:
foo (void)
{
Window root;
xcb_randr_get_providers_cookie_t cookie;
xcb_randr_get_providers_reply_t *reply;
xcb_randr_provider_t *providers;
int nproviders;
xcb_dri3_open_cookie_t *open_cookies;
xcb_dri3_open_reply_t *open_replies;
int ndevices;
root = DefaultRootWindow (compositor.display);
/* Get a list of all providers on the default screen. */
cookie = xcb_randr_get_providers (compositor.conn,
root,
XCB_CURRENT_TIME);
reply = xcb_randr_get_providers_reply (compositor.conn,
cookie, NULL);
if (!reply)
return NULL;
providers = xcb_randr_get_providers_providers (reply);
nproviders = xcb_randr_get_providers_providers_length (reply);
/* Now, open each and every provider. */
open_cookies = alloca (nproviders * sizeof *open_cookies);
open_replies = alloca (nproviders )
}
place point after the last "nproviders", and type:
SPC * SPC s i z e o f SPC * o p e n _ r e p l i e s
nproviders will be mistakenly recognized as a type. I guess because it
looks like a pointer to nproviders to CC Mode.
Thanks.

Thanks for the testing!
I've committed the patch, and I'm closing the bug with this post.
