When the vector reallocated, short strings using SSO were moved together with their inline storage. Previously stored pointers could therefore become dangling and cause environment variables passed to the child process to be corrupted or lost. Build all environment strings first and only then create the pointer array passed to execve. This ensures that the underlying string storage remains stable for the lifetime of the pointer array. commit_hash:039e0f4a94f1eedea47e53e1258b36a7266193df (CpuId) Add AVX512 VNNI feature detection 2026-07-08T15:38:11Z mirali777 mirali777@yandex-team.com 2026-07-08T14:49:48Z urn:sha1:92cad1688d4e77c7f2b6f1b33be3461fe9941882 Adds AVX512 VNNI to NX86 CPU feature detection and cached flags, plus the corresponding CpuId unit-test hook.
