Zig Version
0.15.0-dev.736+b6d904624
Steps to Reproduce and Observed Behavior
Save the following as bug24158.zig and run zig test bug24158.zig
const std = @import("std");
const lastPredefinedSymbol = 53;
const staticSymbols = blk: {
var symbolArray = [_]PointedObject{undefined} ** lastPredefinedSymbol;
for (symbolArray[0..]) |*sym|
initSymbol(sym);
break :blk symbolArray;
};
fn initSymbol(sym: *PointedObject) void {
sym.header = .{
// sym.header = HeapHeader{
.classIndex = .Symbol, .hash = 42, .format = .notIndexable, .age = .static, .length = 1 };
}
test "make it run" {
std.debug.print("in test {}\n", .{&staticSymbols[0]});
}
const PointedObject = packed struct {
header: HeapHeader,
data: packed union {
int: i64,
unsigned: u64,
},
};
const HeapHeader = packed struct(u64) {
classIndex: ClassIndex = .none,
hash: u24 = 0,
format: Format = .free,
immutable: bool = false,
age: Age = .nursery,
length: u11 = 0,
forwarded: bool = false,
};
const Age = enum(u4) {
nursery,
static,
};
const Format = enum(u7) {
notIndexable, // this is an Object with no indexable values
free,
};
const ClassIndex = enum(u16) {
none = 0,
Symbol,
};Compiler goes into an infinite loop. (also happened at least in some 0.14 versions). This is on aarch64/macos
Expected Behavior
Compiler to find errors or get on with the test.
Replacing the tuple with the struct name resolves the problem.
