I dunno; I've never tried Zig before, and it wasn't hard to check whether this kind of bug was easy to have:

  const std = @import("std");
  
  pub fn main() !void {
      var gpa: std.heap.GeneralPurposeAllocator(.{})=.{};
      const alloc=gpa.allocator();
  
      var list = try std.ArrayList(u8).initCapacity(alloc, 1);
      const a = try list.addOne();
      a.* = 0;
      std.debug.print("a={}\n", .{a.*});
      const b = try list.addOne();
      b.* = 0;    
      std.debug.print("a={}\n", .{a.*});
      std.debug.print("b={}\n", .{b.*});
  }


  a=0
