A developer discovered that Zig's libc rewrite introduced a Shlemiel-the-Painter bug causing SQLite INSERT operations to degrade from milliseconds to minutes under load. The quadratic complexity emerged when processing ~40,000 JSON records in a chess analysis service, revealing how basic algorithmic pitfalls can resurface in modern systems.
Background
Joel Spolsky's 2001 essay described the Shlemiel the Painter pattern as an example of how naive algorithmic choices lead to quadratic complexity. This case illustrates the pattern reappearing in modern systems built with newer languages like Zig.
