[stage2][miscompilation] threadlocal variable pointer vs comptime

[xxxbxxx]

Zig Version

zig-0.10.0-dev.4437+1e963053d

Steps to Reproduce

threadlocal var global: u32 = 23;
threadlocal var global_ptr: *u32 = &global;

pub fn main() !void {
  if (global_ptr.* != 23) unreachable;
}

Expected Behavior

stage1 rejects the code:

./zig  build-exe repro.zig  -fstage1
./repro.zig:2:36: error: cannot store runtime value in compile time variable
threadlocal var global_ptr: *u32 = &global;
                                   ^

Actual Behavior

compiles with stage2, and crashes

Segmentation fault at address 0x8
./repro.zig:5:7: 0x20ff0d in main (repro)
  if (global_ptr.* != 23) unreachable;
