RipGrep musl binaries occasionally segfault during very-large searches

RipGrep's x86_64-unknown-linux-musl binaries occasionally crash with a segmentation fault during very-large searches due to heap metadata corruption in musl's memory allocator during concurrent directory operations. The issue occurs when searching large file trees (20GB+ with millions of files) at high concurrency, with crashes typically appearing within minutes on multi-core systems. The problem is traced to a failing integrity assertion in musl's mallocng allocator during a calloc call from opendir.
