Segmentation fault when returning var

[AndreaOrru]

Minimal example:

fn metafoo(comptime function: var) var {
    return function;
}

fn foo() void {}

pub fn main() void {
    _ = metafoo(foo);
}

For context, specifying the return value explicitly works:

fn metafoo(comptime function: var) @typeOf(function) {
    return function;
}

this is #447

but I'll leave this open, at least I can make it print a compile error instead of segfaulting.

This is still crashing in some cases

First case: gives compile error (good)

fn badFunction() var { return 0; }
test "" { _ = badFunction(u32); }

Output:

/home/dbandstra/oxid/test.zig:1:1: error: TODO implement inferred return types https://github.com/ziglang/zig/issues/447
fn badFunction() var {
^
The following command exited with error code 1 [...]

Second case: crashes with message

fn badFunction(comptime T: type) var { return 0; }
test "" { _ = badFunction(u32); }

Output:

TODO implement inferred return types https://github.com/ziglang/zig/issues/447
The following command exited with error code 1 [...]

Third case: crashes with no message

fn badFunction(comptime T: type) var { return 0; }
test "" { _ = comptime badFunction(u32); }

Output:

The following command exited with error code 1 [...]

#5834 is a duplicate of this. (Thanks, @Snektron.)

On the side, Godbolt reported this as error code 255, not error code 1. Not sure if that's how it tries to report segfaults?
