segfault when accidentally calling a tagged union field

[travisstaloch]

Zig Version

0.12.0-dev.2158+4f2009de1

Steps to Reproduce and Observed Behavior

When I accidentally used a field name as a method it caused the compiler to segfault:

// /tmp/tmp.zig
const U = union(enum) {
    int: isize,
    float: f64,
};
test {
    const f = U{ .float = 20 };
    std.debug.print("{}\n", .{f.int()});
}

/tmp $ zig test /tmp/tmp.zig
Segmentation fault (core dumped)

Expected Behavior

some kind of error message and no segfault
