Two arm64-specific miscompiles induce bugs in curl

curl maintainer Daniel Stenberg reported two arm64-specific compiler miscompiles that introduced bugs into curl. The issue highlights the challenges of cross-architecture compiler optimization and the importance of architecture-specific testing in open-source projects.

Background

curl is one of the most widely used open-source HTTP client libraries, maintained by Daniel Stenberg. ARM64 (AArch64) has become a major platform for both servers and consumer devices, making architecture-specific compiler issues increasingly relevant.
