vim c syntax does not support ansi anonymous array

[Jerome Abela]

Binary package hint: vim-runtime

When editing the following file, which use a standard ANSI syntax, the syntax highlighting is wrong for every curly brackets starting at the anonymous array.

#include <stdio.h>

int main() {
    printf("%p\n", (int[]){42});
}

Confirmed. I don't think it's a bug that this happens by default, since ':help c.vim' documents ':let c_no_c99=1' as a way to permit C99 standard items and compound literals are new in C99. However, setting c_no_c99 is not sufficient to remove the error highlighting on the braces here, and it should be.

As a workaround, you can run ':let c_no_curly_error=1' before setting the syntax (or in .vimrc).

Still seeing this issue in Ubuntu 20.
