What did you do? tmpl.v:

module main

pub struct Foo {
	x int
}

pub fn (foo Foo) str() string {
	return 'Foo.x = $foo.x'
}

pub struct Bar<T> {
	t T
}

fn (bar Bar<T>) str() string {
	return 'Bar.t = $bar.t.str()'
}

pub type MyFoo = Foo                    
//pub type BarMyFooArray = Bar<[]Foo>   // (20)
pub type BarMyFooArray = Bar<[]MyFoo>    // (21)

fn main() {
	_ := BarMyFooArray{}
}

// this file compiles with c error
// uncommenting line (20) and commenting (21) => compiles fine

What did you expect to see? v tmpl.v without error

What did you see instead?

/tmp/v_1000/type.2755742234228901151.tmp.c:12148: warning: cast between pointer and integer of different size
tcc: error: undefined symbol 'Array_main__Foo_str'

==================
C error. This should never happen.
