ARM64 compiler bugs in GCC and Rust open vulnerabilities in curl

GCC 15/16 contain an ARM64 optimization bug that miscompiles curl

curl security researcher Viktor Szakáts found two ARM64-only compiler miscompiles that silently produced vulnerable machine code in curl: one in GCC 15/16, one in Rust. The bugs turn optimization errors into exploitable flaws that appear only on ARM64 hardware, from Apple Silicon Macs to AWS Graviton servers.
