Describe the bug

A C error is generated when you try to create a fixed size array with [2]int{init: [5, 10]} syntax. (I see now after looking at the docs that you're supposed to use [5, 10]!)

Reproduction Steps

struct Foo {
	stack_arr [2]string
}

fn main() {
	foo := Foo{[2]string{init: ['a', 'b']}}
}

Expected Behavior

Expected a V error pointing me to [0, 1, ...]! syntax instead.

Current Behavior

C:/Users/imado/AppData/Local/Temp/v_0/test.3082261231298871398.tmp.c:498: warning: WINVER redefined
C:/Users/imado/AppData/Local/Temp/v_0/test.3082261231298871398.tmp.c:6791: warning: implicit declaration of function 'tcc_backtrace'
C:/Users/imado/AppData/Local/Temp/v_0/test.3082261231298871398.tmp.c:12556: error: cannot convert 'struct array' to 'unsigned char *'
builder error: 
==================
C error. This should never happen.
